Re: Change PS1 when running as administrator

If we are looking for other alternatives the GROUPS environment variable can also be used:

PS1='\[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n\$ '
for G in "${GROUPS[@]}"; do
     if [ "$G" = 544 ]; then
         PS1='\[\e]0;Administrator \w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n# '
     fi
done

Speaking of alternatives,

For matching in bash, something like

    [[ $(id -G) =~ \b544\b ]]

was suggested (the suggestion used symbolic name instead of a number and
didn't use word boundary). Seems like word boundary is needed, but I
couldn't get this to work. Are the regex boundary matchers not
supported  by bash =~ operator?  Can use something like

    id -G | grep -q "\b544\b"

(or echo ${GROUPS[@]} | ...)
