Pass it through another cut, then, so like:
GECOS=`grep $USERNAME /etc/passwd | cut -f5 -d: | cut -f1 -d,`
Note that you need to fiddle with it a bit if your GECOS entries are of
the form Last, First Middle, Lots-of-other-data. In that case, you can cut
-f1-2 -d, instead. =)
Of course, there are a million ways to do this. There's
GECOS=`awk -F : "/^$USERNAME\:/ { print \$5 }" < /etc/passwd`
.. then pass that through anything that extracts the name. =) Even awk,
which can also handle rearranging names. Isn't it sooo cool?
