Add fzf to get fuzzy search for your history. I reuse long complicated commands all the time by pressing Ctrl+R and then typing the first letters of a few words I remember using.

It's also useful to remove duplicate commands and store infinite history. Add this to ~/.bashrc:

  export HISTFILESIZE=
  export HISTSIZE=
  export HISTCONTROL=ignoredups

Changing HISTFILE by context has been a huge win, keeping commands from generic system administration or different projects from getting in the way as I search back through my history to do a thing again.

Cmd/Ctrl-F in general is probably the biggest invisible time-saver if you can count UX patterns.

Try fzf for history management, it's a life changer.

The 'history' command is helpful the 1% of the time Ctrl-R and Ctrl-S fail you.

Bash alias. And my large bash_alias file

You can also add a comment for searchability, as in:

    > big hairy command with --lots --of arguments  # foobar

Then you can search for 'foobar' via fzf or whatnot.

Give hstr a try: https://github.com/dvorka/hstr

It's saved me countless hours over the years as it's just so much better than regular CTRL-R. I also find it to work better than fzf.
