But why should one use *cat* here?

Antonio> cat file1 | awk '{print $1}' >x1
Antonio> cat file2 | awk '{print $1}' >x2

Sorry.  You struck my "unnecessary use of cat" nerve.

Get a clue, newbie script writers.  Cat with one parameter is *rarely*
needed.  For y'all, *never* is closer, but there are a few cases where
it might come in useful.

Grmph.

(And look, I didn't rewrite the script in Perl.  Tsk tsk. :-)
