# 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.
