+
+A cross platform solution to node's spawn and spawnSync.
+
+
+## Installation
+
+`$ npm install cross-spawn`
+
+
+## Why
+
+Node has issues when using spawn on Windows:
+
+- It ignores [PATHEXT](https://github.com/joyent/node/issues/2318)
+- It does not support [shebangs](https://en.wikipedia.org/wiki/Shebang_(Unix))
+- Has problems running commands with [spaces](https://github.com/nodejs/node/issues/7367)
+- Has problems running commands with posix relative paths (e.g.: `./my-folder/my-executable`)
+- Has an [issue](https://github.com/moxystudio/node-cross-spawn/issues/82) with command shims (files in `node_modules/.bin/`), where arguments with quotes and parenthesis would result in [invalid syntax error](https://github.com/moxystudio/node-cross-spawn/blob/e77b8f22a416db46b6196767bcd35601d7e11d54/test/index.test.js#L149)
+- No `options.shell` support on node `<v4.8`
+
+All these issues are handled correctly by `cross-spawn`.
+There are some known modules, such as [win-spawn](https://github.com/ForbesLindesay/win-spawn), that try to solve this but they are either broken or provide faulty escaping of shell arguments.
+
+
+## Usage
+
+Exactly the same way as node's [`spawn`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options) or [`spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options), so it's a drop in replacement.
+
+
+```js
+const spawn = require('cross-spawn');
+
+// Spawn NPM asynchronously
+const child = spawn('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
+
+// Spawn NPM synchronously
+const result = spawn.sync('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
+```
+
+
+## Caveats
+
+### Using `options.shell` as an alternative to `cross-spawn`
+
+Starting from node `v4.8`, `spawn` has a `shell` option that allows you run commands from within a shell. This new option solves
+the [PATHEXT](https://github.com/joyent/node/issues/2318) issue but:
+
+- It's not supported in node `<v4.8`
+- You must manually escape the command and arguments which is very error prone, specially when passing user input
+- There are a lot of other unresolved issues from the [Why](#why) section that you must take into account
+
+If you are using the `shell` option to spawn a command in a cross platform way, consider using `cross-spawn` instead. You have been warned.
+
+### `options.shell` support
+
+While `cross-spawn` adds support for `options.shell` in node `<v4.8`, all of its enhancements are disabled.
+
+This mimics the Node.js behavior. More specifically, the command and its arguments will not be automatically escaped nor shebang support will be offered. This is by design because if you are using `options.shell` you are probably targeting a specific platform anyway and you don't want things to get into your way.
+
+### Shebangs support
+
+While `cross-spawn` handles shebangs on Windows, its support is limited. More specifically, it just supports `#!/usr/bin/env <program>` where `<program>` must not contain any arguments.   
+If you would like to have the shebang support improved, feel free to contribute via a pull-request.
+
+Remember to always test your code on Windows!
+
+
+## Tests

+semver.valid('1.2.3') // '1.2.3'
+semver.valid('a.b.c') // null
+semver.clean('  =v1.2.3   ') // '1.2.3'
+semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+semver.gt('1.2.3', '9.8.7') // false
+semver.lt('1.2.3', '9.8.7') // true
+semver.minVersion('>=1.0.0') // '1.0.0'
+semver.valid(semver.coerce('v2')) // '2.0.0'
+semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
+```
+
+As a command-line utility:
+
+```
+$ semver -h
+
+A JavaScript implementation of the https://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+        Print versions that match the specified range.
+
+-i --increment [<level>]
+        Increment a version by the specified level.  Level can
+        be one of: major, minor, patch, premajor, preminor,
+        prepatch, or prerelease.  Default level is 'patch'.
+        Only one version may be specified.
+
+--preid <identifier>
+        Identifier to be used to prefix premajor, preminor,
+        prepatch or prerelease version increments.
+
+-l --loose
+        Interpret versions and ranges loosely
+
+-p --include-prerelease
+        Always include prerelease versions in range matching

+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<https://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+Note that this behavior can be suppressed (treating all prerelease
+versions as if they were normal versions, for the purpose of range
+matching) by setting the `includePrerelease` flag on the options
+object to any
+[functions](https://github.com/npm/node-semver#functions) that do
+range matching.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta')
+// '1.2.4-beta.0'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```bash
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any version satisfies)
+* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero digit in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0`
+* `^0.2.3` := `>=0.2.3 <0.3.0`
+* `^0.0.3` := `>=0.0.3 <0.0.4`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0`
+* `^0.0.x` := `>=0.0.0 <0.1.0`
+* `^0.0` := `>=0.0.0 <0.1.0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0`
+* `^0.x` := `>=0.0.0 <1.0.0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `options` object argument.  All
+options in this object are `false` by default.  The options supported
+are:
+
+- `loose`  Be more forgiving about not-quite-valid semver strings.
+  (Any resulting output will always be 100% strict compliant, of
+  course.)  For backwards compatibility reasons, if the `options`
+  argument is a boolean value instead of an object, it is interpreted
+  to be the `loose` param.
+- `includePrerelease`  Set to suppress the [default
+  behavior](https://github.com/npm/node-semver#prerelease-tags) of
+  excluding prerelease tagged versions from ranges unless they are
+  explicitly opted into.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
+  or comparators intersect.
+* `parse(v)`: Attempt to parse a string as a semantic version, returning either
+  a `SemVer` object or `null`.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+### Comparators
+
+* `intersects(comparator)`: Return true if the comparators intersect
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minVersion(range)`: Return the lowest version that can possibly match
+  the given range.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+* `intersects(range)`: Return true if any of the ranges comparators intersect
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.
+
+### Coercion
+
+* `coerce(version)`: Coerces a string to semver if possible
+
+This aims to provide a very forgiving translation of a non-semver string to
+semver. It looks for the first digit in a string, and consumes all
+remaining characters which satisfy at least a partial semver (e.g., `1`,
+`1.2`, `1.2.3`) up to the max permitted length (256 characters).  Longer
+versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`).  All
+surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
+`3.4.0`).  Only text which lacks digits will fail coercion (`version one`
+is not valid).  The maximum  length for any semver component considered for
+coercion is 16 characters; longer components will be ignored
+(`10000000000000000.4.7.4` becomes `4.7.4`).  The maximum value for any
+semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
+components are invalid (`9999999999999999.4.7.4` is likely invalid).

+# which
+
+Like the unix `which` utility.
+
+Finds the first instance of a specified executable in the PATH
+environment variable.  Does not cache the results, so `hash -r` is not
+needed when the PATH changes.
+
+## USAGE
+
+```javascript
+var which = require('which')
+
+// async usage
+which('node', function (er, resolvedPath) {
+  // er is returned if no "node" is found on the PATH
+  // if it is found, then the absolute path to the exec is returned
+})
+
+// sync usage
+// throws if not found
+var resolved = which.sync('node')
+
+// if nothrow option is used, returns null if not found
+resolved = which.sync('node', {nothrow: true})
+
+// Pass options to override the PATH and PATHEXT environment vars.
+which('node', { path: someOtherPath }, function (er, resolved) {
+  if (er)
+    throw er
+  console.log('found at %j', resolved)
+})
+```
+
+## CLI USAGE
+
+Same as the BSD `which(1)` binary.
+
+```
+usage: which [-as] program ...
+```
+
+## OPTIONS
+
+You may pass an options object as the second argument.
+
+- `path`: Use instead of the `PATH` environment variable.
+- `pathExt`: Use instead of the `PATHEXT` environment variable.
+- `all`: Return all matches, instead of just the first one.  Note that
+  this means the function returns an array of strings instead of a
+  single string.

+
+> A better [`child_process`](https://nodejs.org/api/child_process.html)
+
+
+## Why
+
+- Promise interface.
+- [Strips EOF](https://github.com/sindresorhus/strip-eof) from the output so you don't have to `stdout.trim()`.
+- Supports [shebang](https://en.wikipedia.org/wiki/Shebang_(Unix)) binaries cross-platform.
+- [Improved Windows support.](https://github.com/IndigoUnited/node-cross-spawn#why)
+- Higher max buffer. 10 MB instead of 200 KB.
+- [Executes locally installed binaries by name.](#preferlocal)
+- [Cleans up spawned processes when the parent process dies.](#cleanup)
+
+
+## Install
+
+```
+$ npm install execa
+```

+</a>
+
+
+## Usage
+
+```js
+const execa = require('execa');
+
+(async () => {
+	const {stdout} = await execa('echo', ['unicorns']);
+	console.log(stdout);
+	//=> 'unicorns'
+})();
+```
+
+Additional examples:
+
+```js
+const execa = require('execa');
+
+(async () => {
+	// Pipe the child process stdout to the current stdout
+	execa('echo', ['unicorns']).stdout.pipe(process.stdout);
+
+
+	// Run a shell command
+	const {stdout} = await execa.shell('echo unicorns');
+	//=> 'unicorns'
+
+
+	// Catching an error
+	try {
+		await execa.shell('exit 3');
+	} catch (error) {
+		console.log(error);
+		/*
+		{
+			message: 'Command failed: /bin/sh -c exit 3'
+			killed: false,
+			code: 3,
+			signal: null,
+			cmd: '/bin/sh -c exit 3',
+			stdout: '',
+			stderr: '',
+			timedOut: false
+		}
+		*/
+	}
+})();
+
+// Catching an error with a sync method
+try {
+	execa.shellSync('exit 3');
+} catch (error) {
+	console.log(error);
+	/*
+	{
+		message: 'Command failed: /bin/sh -c exit 3'
+		code: 3,
+		signal: null,
+		cmd: '/bin/sh -c exit 3',
+		stdout: '',
+		stderr: '',
+		timedOut: false
+	}
+	*/
+}
+```

+
+## API
+
+### execa(file, [arguments], [options])
+
+Execute a file.
+
+Think of this as a mix of `child_process.execFile` and `child_process.spawn`.
+
+Returns a [`child_process` instance](https://nodejs.org/api/child_process.html#child_process_class_childprocess), which is enhanced to also be a `Promise` for a result `Object` with `stdout` and `stderr` properties.
+
+### execa.stdout(file, [arguments], [options])
+
+Same as `execa()`, but returns only `stdout`.
+
+### execa.stderr(file, [arguments], [options])
+
+Same as `execa()`, but returns only `stderr`.
+
+### execa.shell(command, [options])
+
+Execute a command through the system shell. Prefer `execa()` whenever possible, as it's both faster and safer.
+
+Returns a [`child_process` instance](https://nodejs.org/api/child_process.html#child_process_class_childprocess).
+
+The `child_process` instance is enhanced to also be promise for a result object with `stdout` and `stderr` properties.
+
+### execa.sync(file, [arguments], [options])
+
+Execute a file synchronously.
+
+Returns the same result object as [`child_process.spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options).
+
+This method throws an `Error` if the command fails.
+
+### execa.shellSync(file, [options])
+
+Execute a command synchronously through the system shell.
+
+Returns the same result object as [`child_process.spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options).
+
+### options
+
+Type: `Object`
+
+#### cwd
+
+Type: `string`<br>
+Default: `process.cwd()`
+
+Current working directory of the child process.
+
+#### env
+
+Type: `Object`<br>
+Default: `process.env`
+
+Environment key-value pairs. Extends automatically from `process.env`. Set `extendEnv` to `false` if you don't want this.
+
+#### extendEnv
+
+Type: `boolean`<br>
+Default: `true`
+
+Set to `false` if you don't want to extend the environment variables when providing the `env` property.
+
+#### argv0
+
+Type: `string`
+
+Explicitly set the value of `argv[0]` sent to the child process. This will be set to `command` or `file` if not specified.
+
+#### stdio
+
+Type: `string[]` `string`<br>
+Default: `pipe`
+
+Child's [stdio](https://nodejs.org/api/child_process.html#child_process_options_stdio) configuration.
+
+#### detached
+
+Type: `boolean`
+
+Prepare child to run independently of its parent process. Specific behavior [depends on the platform](https://nodejs.org/api/child_process.html#child_process_options_detached).
+
+#### uid
+
+Type: `number`
+
+Sets the user identity of the process.
+
+#### gid
+
+Type: `number`
+
+Sets the group identity of the process.
+
+#### shell
+
+Type: `boolean` `string`<br>
+Default: `false`
+
+If `true`, runs `command` inside of a shell. Uses `/bin/sh` on UNIX and `cmd.exe` on Windows. A different shell can be specified as a string. The shell should understand the `-c` switch on UNIX or `/d /s /c` on Windows.
+
+#### stripEof
+
+Type: `boolean`<br>
+Default: `true`
+
+[Strip EOF](https://github.com/sindresorhus/strip-eof) (last newline) from the output.
+
+#### preferLocal
+
+Type: `boolean`<br>
+Default: `true`
+
+Prefer locally installed binaries when looking for a binary to execute.<br>
+If you `$ npm install foo`, you can then `execa('foo')`.
+
+#### localDir
+
+Type: `string`<br>
+Default: `process.cwd()`
+
+Preferred path to find locally installed binaries in (use with `preferLocal`).
+
+#### input
+
+Type: `string` `Buffer` `stream.Readable`
+
+Write some input to the `stdin` of your binary.<br>
+Streams are not allowed when using the synchronous methods.
+
+#### reject
+
+Type: `boolean`<br>
+Default: `true`
+
+Setting this to `false` resolves the promise with the error instead of rejecting it.
+
+#### cleanup
+
+Type: `boolean`<br>
+Default: `true`
+
+Keep track of the spawned process and `kill` it when the parent process exits.
+
+#### encoding
+
+Type: `string`<br>
+Default: `utf8`
+
+Specify the character encoding used to decode the `stdout` and `stderr` output.
+
+#### timeout
+
+Type: `number`<br>
+Default: `0`
+
+If timeout is greater than `0`, the parent will send the signal identified by the `killSignal` property (the default is `SIGTERM`) if the child runs longer than timeout milliseconds.
+
+#### buffer
+
+Type: `boolean`<br>
+Default: `true`
+
+Buffer the output from the spawned process. When buffering is disabled you must consume the output of the `stdout` and `stderr` streams because the promise will not be resolved/rejected until they have completed.
+
+#### maxBuffer
+
+Type: `number`<br>
+Default: `10000000` (10MB)
+
+Largest amount of data in bytes allowed on `stdout` or `stderr`.
+
+#### killSignal
+
+Type: `string` `number`<br>
+Default: `SIGTERM`
+
+Signal value to be used when the spawned process will be killed.
+
+#### stdin
+
+Type: `string` `number` `Stream` `undefined` `null`<br>
+Default: `pipe`
+
+Same options as [`stdio`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio).
+
+#### stdout
+
+Type: `string` `number` `Stream` `undefined` `null`<br>
+Default: `pipe`
+
+Same options as [`stdio`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio).
+
+#### stderr
+
+Type: `string` `number` `Stream` `undefined` `null`<br>
+Default: `pipe`
+
+Same options as [`stdio`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio).
+
+#### windowsVerbatimArguments
+
+Type: `boolean`<br>
+Default: `false`
+
+If `true`, no quoting or escaping of arguments is done on Windows. Ignored on other platforms. This is set to `true` automatically when the `shell` option is `true`.
+
+
+## Tips
+
+### Save and pipe output from a child process
+
+Let's say you want to show the output of a child process in real-time while also saving it to a variable.
+
+```js
+const execa = require('execa');
+const getStream = require('get-stream');
+
+const stream = execa('echo', ['foo']).stdout;
+
+stream.pipe(process.stdout);
+
+getStream(stream).then(value => {
+	console.log('child output:', value);
+});
+```
