Is awk worth learning in 2020?

Perl or Python are far better than any version of awk or sed when you have very complex input/output scenarios. The more complex the problem is, the better off you are using python, from a maintenance and readability standpoint.

Is grep faster than sed?

Generally I would say grep is the fastest one, sed is the slowest. Of course this depends on what are you doing exactly. I find awk much faster than sed . You can speed up grep if you don’t need real regular expressions but only simple fixed strings (option -F).

If the -c option is present, then commands are read from string. If there are arguments after the string, they are assigned to the positional parameters, starting with $0. The -c flag tells Bash that the next argument is a string of commands to run instead of the filename of a script.
