This is a simple wrapper for the [os_process] type that allows you to interact with a bash shell, similar to how you would if you were using Terminal on OS X. On Windows, it interacts with the cmd process. The tag creates a new [os_process] type, opens a new shell, and executes whatever command is passed to it.

Parameters

none

Sample Usage

local(x = shell('cd /path/to/file; chmod 664 helloworld.xml'))

Bug in Centos section
There's an omission that cause the method to fail on Centos. Change this: local(shell = os_process('/bin/sh', (:'cd '+#this+'; '+#cmd))) to local(shell = os_process('/bin/sh', (:'-c','cd '+#this+'; '+#cmd))) (As of 2011-07-19)
