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[@]} | ...)
