Grep is fiiiiine.

sed is okay but a little nasty, when your sed script is longer that one search-replace command you gotta ask yourself what you’re doing really (yes, sed is a full-featured Turing-complete programming language, if you go far enough into the man page).

When I see awk in any stackoverflow recipe, I just say ‘fuck it’ and rewrite the whole thing in Python. Python is included into the minimal system image in Debian, the same as awk, but is way less esoteric, and you can do python -e ‘import os, sys; commands;’ for a one-liner console script.

And if you want to talk about portability, try writing scripts for Android 4.4 ash shell. There’s no [ ] command. You do switch/case to compare strings.
