Try to evaluate input data suing awk

WebbSite · 09-25-2014, 12:42 PM

Hello,
I am trying to evalute input data using awk: For example
cat /etc/ssh/sshd_config | grep IgnoreRhosts | awk '{print $1,$2}' | awk '{print} END {if ($1 == "#IgnoreRhosts yes") {print "failure"}} then {if ($1 == "IgnoreRhosts yes") {print "compliant"} else {print "failure"}}' Unfortunately this does not seem to be working. Any ideas?
Thanks in Advance!

Simpler to do this:

Code:

grep '^IgnoreRhosts' /etc/ssh/sshd_config > /dev/null && echo "compliant" || echo "non-compliant"

Or do you absolutely require AWK?

When things fail, add some diagnostics - for example try printing $1 - you might be in for a surprise.
You never need to use cat to feed awk - it reads files just fine. Likewise awk piping to another awk. Awk also has good regex support, so the grep should never be necessary.
KISS.
