Search for a string inside all files in the current directory

grep -RnisI <pattern> *
This is how I typically grep. -R recurse into subdirectories, -n show line numbers of matches, -i ignore case, -s suppress "doesn't exist" and "can't read" messages, -I ignore binary files (technically, process them as having no matches, important for showing inverted results with -v) I have grep aliased to "grep --color=auto" as well, but that's a matter of formatting not function.

What Others Think

I personally prefer to leave the -R out so that I don't always recurse - I can always add it back in if I want, even from an alias.
