I’m trying to write a short shell script for Mac OS X that will disable CoreStorage. To do this I need to capture the first Logical Volume UUID (lvUUID) from the output of "diskutil cs list" and use it in an ensuing command. I am having trouble though and it seems to be a simple issue with grep. Obviously still pretty new to the command line. [more inside]
The Mac OS X Automator tool lets me run a perl script as well shell scripts, but I'd like to use awk instead. How can I fit this into my workflow? Perl appears in the popup menu of possible shells for the script, but awk does not. [more inside]

I would basically like to rip off, wholesale, some command-line script which will provide me a countdown -- only in days. No years, months, minutes, or seconds. Unfortunately, adapting an existing script is beyond my ken. [more inside]
