But do you really want to run "ps" repeatedly for each string?  And do you
want a line of "ps" output to be printed multiple times if more than one
string appears in that line?  How about:

awk ... > /tmp/foo.$$
ps | fgrep -f /tmp/foo.$$
rm -f /tmp/foo.$$

(or set up a "trap" to do the "rm", so the temp file gets removed even if
the script is killed by a signal).
