awk question

  • Follow


I am in the process of writing a script that would read input from a
file containing 2 columns and would screen out and list only the
columns that contain "0".  e.g,.

col 1    col 2
3333      542
4321       0
5541       0
5555       432

so I would want

col 1     col 2
4321       0
5541       0

I am new to programing and would very much like input to get the
results:  The script looke like
awk /^[0]$/ '{ print $1, $2 }' file > file1 2>&1

obviously the above is not working
Thanks

awk '! $1*$2'

will do the job and even preserve your header.
