# 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.
