I have a configuration file which is a simple text. I want to list some configuration line but except some sitring. How can I use Linux grep to exclude and search for given strings? Thanks in advance for your help!
There are different ways to exclude and grep given a text file or input stream. I generally prefer the most basic one where use two grep where the first one is for exclude with -v option and pipe to second one where I grep for my string. grep -v 'able' config.txt | grep 'system' For more information look https://www.poftut.com/introduction-to-linux-grep-command-with-examples/
