Ctrl+R Searches Your Entire Shell History And Ive Been Pressing The Up Arrow For Years

ctrl+R in steps:

1. Press Ctrl+R. 2 👍 Type part of a previous command. 3 🤦 Ctrl+R again for older matches.
2. Enter to run, or arrow key to edit first.
3. Ctrl+G (bash) or Ctrl+C to cancel.

tip: bash keeps a limited history by default, set HISTSIZE and HISTFILESIZE higher in .bashrc so theres more to search. powerShell on Windows has the same Ctrl+R through PSReadLine.
