convert a sed 1 liner to an awk 1 liner 1

[tumichaelf]

I have am trying to learn awk, and what I want to do is covert

sed -i 's/check_disk\ \-w\ 20\%/check_disk\ \-w\ 15\%/g' /var/tmp/nrpe.cfg

into an awk 1 liner similar to

awk '/^command\[check_disk\]=/&&!/-x \/boot/{$0=$0 " -x /boot"}1' /var/tmp/nrpe.cfg > /var/tmp/nrpe.cfg.new

(written by feherke (

for me in a separate post).

Thanks,

Michael

Like this ?

awk '{sub(/check_disk -w 20%/,"check_disk -w 15%");print}' /var/tmp/nrpe.cfg > /var/tmp/nrpe.cfg.new

Hope This Helps, PH.
