Thanks again!

My bash skills are a bit rusty, so it's a pleasure to receive pointers like this from someone who knows better

I'll be posting a whole article on Bash variables later on, and will be sure to include your comments.

There is also variable $LOGNAME filled with user name.
Only $USER and $LOGNAME is suitable for portable Born shell-like scripts (sh, ksh, bash, zsh). The $USER is known also in csh/tcsh.

You can see all groups by echo ${GROUPS[*]} or ${GROUPS[@]} (first item in array is primary group /use newgrp to change/)

Sorry for splitting into 2 posts.

You can use also $UID, $EUID and $GROUPS in bash.
