history

Show previously run commands

history lists all commands from current and past sessions (stored in ~/.bash_history). history | grep docker finds recent docker commands. !456 re-runs command 456.

Example

$ history | tail -3
 1236  tail -f /var/log/app.log
 1237  grep ERROR /var/log/app.log | wc -l
 1238  history
