[shell]

Description

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, switches the current working directory to the folder from which the tag was called, and executes whatever command is passed to it. Requires [response_localfolder] and only loads if the [os_process] type is loaded.

Sample Usage

shell('echo foo');

-> foo
