what are some things that you find confusing about the command line? Mostly interested in answers from people who use the (unix) command line but still don't feel very comfortable with it.
(thinking of writing about using the command line interactively but I'm unsure about whether that would actually be helpful)
Follow
@b0rk The various initialization files (.profile, .bash_profile, .bashrc), how they relate, and when to use each. (I've been running into situations recently where the answer is "none of them, you need .zprofile" and I don't really understand why.)
Also took me a long time to understand combinations like ">log.txt 2>&1" versus "2>&1 >log.txt"
