# cmd-shim
The cmd-shim used in npm to create executable scripts on Windows,
since symlinks are not suitable for this purpose there.
On Unix systems, you should use a symbolic link instead.

[](https://www.npmjs.com/package/cmd-shim)
## Installation
```
npm install cmd-shim
```
## API
### cmdShim(from, to, cb)
Create a cmd shim at `to` for the command line program at `from`.
e.g.
```javascript
var cmdShim = require('cmd-shim');
cmdShim(__dirname + '/cli.js', '/usr/bin/command-name', function (err) {
if (err) throw err;
});
```
### cmdShim.ifExists(from, to, cb)
The same as above, but will just continue if the file does not exist.
Source:
```javascript
function cmdShimIfExists (from, to, cb) {
fs.stat(from, function (er) {
if (er) return cb()
cmdShim(from, to, cb)
})
}
```
