$ !9

Executes the last command you used:

$ !!

This represents only the very last word (argument) of the previous command:

$ !$

Delete the offset, being the number you have in your history for a command:

$ history -d offset

Append history lines from this session to .bash_history:

$ history -a

Synchronize the history lines from several virtual terminals:

$ history -n

If you manually edited the .bash_history file:

$ history -r

Display that line of the history (without executing it):

$ history -p \!28

Display a range of lines from the history:

$ history -p \!2{5..8}

Search the most recent command that starts with "ls" and show the first argument:
