Quick Tip: Track Your Bash History

  Sometimes, you want to look back in time and see what commands you ran in the past. Thanks to the history command built into the Linux shell, you can do that with ease.

$ history
...
396  git pull --all
397  git branch -a
398  git push origin :header-revamp
399  git branch -a
400  git push origin :nav-dropdown
401  git branch -d nav-dropdown
402  git fetch -p origin
403  git branch -a
404  git checkout front-page
405  git branch --unset-upstream
406  git checkout develop
...

You can easily search through the output by piping to the grep command.

$ history | grep ssh
482  ssh
492  ssh -p xxxx [email protected]
702  ssh -p xxxx [email protected]
770  ssh -p xxxx
