isexe

Minimal module to check if a file is executable.

Uses fs.access if available, and tests against the PATHEXT environment variable on Windows.

USAGE

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.access or 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 when using the mode approach.
gid Number to use as the group id when using the mode approach.
pathExt List of path extensions to use instead of PATHEXT environment variable on Windows.
