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

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

## <tt>isexe(path, [options], [callback])</tt>

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.

## <tt>isexe.sync(path, [options])</tt>

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.
