A failed attempt to install a Homebrew package on a Maverick OSX Macbook Pro was terminated by a Cntrl-C process break. Afterwards, the ZSH shell profile is corrupted such that :
uname zsh: command not found: uname
man zsh: command not found: man
ps zsh: command not found: ps
cat zsh: command not found: cat
echo $PATH /usr/sbin:/usr/local/bin:/usr/local/bin:/usr/local/bin:/usr/local/sbin:PATH:/usr/local/opt/curl/bin
