The ! prefix is used to access previous commands.

Other useful commands:

• !$ - last argument from previous command
• !^ - first argument (after the program/built-in/script) from previous command
• !! - previous command (often pronounced "bang bang")
• !n - command number n from history
• !pattern - most recent command matching pattern
• !!:s/find/replace - last command, substitute find with replace
