Why not just:
ipaddy=`awk '{ print $1 }' ipin.txt`
But that still doesn't get you a comma-separated list.
Erm, a Perl list?

Hey, if you throw an @ in front of ipaddy you get a Perl list.
But I think the answer that is really wanted is
ipaddy=$(perl -lne 'push @a, (split)[0];END {print join ",", @a}'
file_with_the_data);
Or:
ipaddy=$(perl -lane'[EMAIL PROTECTED],$F[0]}{$,=",";[EMAIL PROTECTED]'
file_with_the_data);
