$ cat pipe.js 
require('shelljs/global')
echo('files with o\'s in the name:\n' + ls().grep('o'));

$ shjs pipe.js 
/home/pelle/pipe.js:3
echo('files with o\'s in the name:\n' + ls().grep('o'));
                                             ^

Hi @hjek!

I think the problem is most likely that you're using shelljs 0.6 (which is currently on npm), where as the README on master is the development version, which is 0.7. Can you confirm that this is the case?

Thanks!

That was the problem, and the documentation on there also doesn't mention pipes.

The README is still the best place to check for docs, but it documents all the new features that may or may not be released yet. I'll add a warning to the top of the README to clarify this.
