#24I have a super neat one but it's on my work machine. Not strictly a one-liner but definitely a CLI QoL improvement. It allows me to type a partial command, for e.g. up to where a file path might be, hit a hotkey to invoke (e.g.) fzf, and finally have fzf's output inserted where my cursor was in the command. Uses some vars that readline exposes. I haven't taken it beyond inserting paths yet, but you could imagine you…

#291) Whenever building anything; 2>&1 | tee build.log | grep 2) Do everything within GNU Screen window with CTRL-A + Shift-H to log all output to logfile i.e. "screenlog. ". Both lifesavers when working with multiple systems and codebases. 3) Always use "set -o vi" with bash so that i can use vi/vim keybindings across everything.

tmux users can use it's `capture-pane` command, either before or after the fact if history is set big enough. There are several helpful flags worth researching.
e.g. `tmux capture-pane -pS - > ~/tmux.log` in a shell to save the history of that pane, or just `prefix+: capture-pane ...` from within tmux
