When I changed the second script into the following:
Code:
BEGIN {FS=" "}
$2~/utah/
{
      print $2 ", " $1
}

The output became:
Quote:
272 lab2-19:~> awk -f new.awk directory
abs utah 12343
utah, abs
cde utah 230548
utah, cde
tar, asf
lasfj utah 2057
utah, lasfj

OK, I know now, it must be written this way:
Code:
BEGIN {FS=" "}
$2~/utah/{
      print $2 ", " $1
}
