# fm v1.2 by Kiah Morante
# A very simple file manager.
# Depends on pycp/pymv, http://github.com/yannicklm/pycp
# 'source' this file in a BASH shell

showHidden=0 # Hidden files not shown
showDetails=0 # ls is replaced with ls -l if showDetails is 1

# So that the user knows if they have root privileges:

if [[ $(whoami) == 'root' ]]; then
    PS1="\[\e[0;32\]mf\[m\e[m\] \[\e[0;31m\]root\[\e[m\] \[\e[0;34m\]\w \[\e[m\]\[\e[0;31m\]> \[\e[m\]"
else
    PS1="\[\e[0;32\]mf\[m\e[m\] \[\e[0;34m\]\w \[\e[m\]\[\e[0;31m\]> \[\e[m\]"
