*Tweet*  Useless use of cat.  Five yards, repeat the down.

grep -v RGB foo | awk '{ print $1 }'


And before someone tweets me to a taste of my own medicine, note you
don't even need the grep (or whitespace even :) since awk can do the
match internally itself just as well:


awk '!/RGB/{print$1}' zorch


Of course you can do the same with perl just as easily:


perl -lane 'print$F[0]if!/RGB/' zorch
