I'm running Mavericks, latest DP (legit I'd like to add).
Shell:
/bin/bash (out-of-the-box)
GNU bash, version 3.2.51(1)-release (x86_64-apple-darwin13)
Copyright © 2007 Free Software Foundation, Inc.
Finder:
select my homefolder
Command (nothing works):
touch HelloWorld.txt
/usr/bin/touch HelloWorld.txt
I do have HomeBrew installed, but I assume that's not relevant for the command above.
Your help is greatly appreciated!
