Enter IP at the end of a specific line












1















I have the following file.txt that follows the same pattern and I want to modify it where this file is by adding an ip:



# gfhfhgfh

gfhfghgfhgfhgfh

MACs 

# access

USER CONSOLA *,!10.249.247.3,!10.249.245.65

/bin/false


I want to add an ip in the end of the line that contains as patron USER CONSOLE:



 USER CONSOLA *,!10.249.247.4,!10.249.245.65,!10.249.245.90,


I only manage to add the ip in the whole document at the moment but not in that particular line the code used is



sed 's/r?$/,!10.10.11.1/' file.txt





linux text-processing scripting ip-address
