# 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.

### 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.
