As we are doing more and more commands at the bash-prompt it's time to
learn a neat little trick:
As you are at an empty prompt press the "arrow-up" key and you will see
the previous command you typed in !
Press again, and again, and again, see all the commands that were
stored in the "bash-history"
As current user you will only see the commands you typed in, as root
you will see the commands you typed in as root.
More fun, type in:
And you'll get a full numbered list of all stored commands
Will get you number 8 of that list
And you will get the last command that started with v
Ctrl+R will let you do a search in the history
Bash history won't be lost at reboot or shutdown, clever isn't it ?
