1# isexe
2
3Minimal module to check if a file is executable, and a normal file.
4
5Uses `fs.stat` and tests against the `PATHEXT` environment variable on
6Windows.
7
8## USAGE
9
10```javascript
11var isexe = require('isexe')
12isexe('some-file-name', function (err, isExe) {
13 if (err) {
14 console.error('probably file does not exist or something', err)
15 } else if (isExe) {
16 console.error('this thing can be run')
17 } else {
18 console.error('cannot be run')
19 }
20})
21
22// same thing but synchronous, throws errors
23var isExe = isexe.sync('some-file-name')
24
25// treat errors as just "not executable"
26isexe('maybe-missing-file', { ignoreErrors: true }, callback)
27var isExe = isexe.sync('maybe-missing-file', { ignoreErrors: true })
28```

30## API
31
32### `isexe(path, [options], [callback])`
33
34Check if the path is executable. If no callback provided, and a
35global `Promise` object is available, then a Promise will be returned.
36
37Will raise whatever errors may be raised by `fs.stat`, unless
38`options.ignoreErrors` is set to true.
39
40### `isexe.sync(path, [options])`
41
42Same as `isexe` but returns the value and throws any errors raised.
43
44### Options
45
46* `ignoreErrors` Treat all errors as "no, this is not executable", but
47 don't raise them.
48* `uid` Number to use as the user id
49* `gid` Number to use as the group id
50* `pathExt` List of path extensions to use instead of `PATHEXT`
51 environment variable on Windows.
