You can easily do it with sed:

sed '/^mon host =/ s/$/, 2.2.2.2/' your.conf

Use -i to change the file instead of printing to STDOUT.

I dont know why but your command delete inside the file. but this is works "sed 's/mon host = .*/&, 2.2.2.2/' my.conf -i" Thank you for your help. – Morphinz Dec 08 '17 at 12:58
