isexe

Minimal module to check if a file is executable, and a normal file.

Uses fs.stat and tests against the PATHEXT environment variable on Windows.

USAGE

```javascript var isexe = require('isexe') isexe('some-file-name', function (err, isExe) { if (err) { console.error('probably file does not exist or something', err) } else if (isExe) { console.error('this thing can be run') } else { console.error('cannot be run') } })

// same thing but synchronous, throws errors var isExe = isexe.sync('some-file-name')

// treat errors as just "not executable" isexe('maybe-missing-file', { ignoreErrors: true }, callback) var isExe = isexe.sync('maybe-missing-file', { ignoreErrors: true }) ```

API

isexe(path, [options], [callback])

Check if the path is executable. If no callback provided, and a global Promise object is available, then a Promise will be returned.

Will raise whatever errors may be raised by fs.stat, unless options.ignoreErrors is set to true.

isexe.sync(path, [options])

Same as isexe but returns the value and throws any errors raised.

Options

• ignoreErrors Treat all errors as "no, this is not executable", but don't raise them.
• uid Number to use as the user id
• gid Number to use as the group id
• pathExt List of path extensions to use instead of PATHEXT environment variable on Windows.
