Command History (UNIX in a Nutshell: System V Edition)

5.5. Command History

`!`	Begin a history substitution
`!!`	Previous command
`!``N`	Command number N in history list
`!-``N`	Nth command back from current command
`!``string`	Most recent command that starts with string
`!?``string``?`	Most recent command that contains string
`!?``string``?%`	Most recent command argument that contains string
`!$`	Last argument of previous command
`!!``string`	Previous command, then append string
`!``N string`	Command N, then append string
`!{``s1``}s2`	Most recent command starting with string s1, then append string s2
`^``old``^new^`	Quick substitution; change string old to new in previous command; execute modified command

The following command is assumed:

`:0`	Command name
`:``n`	Argument number n
`^`	First argument
`$`	Last argument

`-``m`	Words 0 through m; same as `:0-`m
`:``n``-`	Arguments n through next-to-last
`:``n``*`	Arguments n through last; same as n`-$`
`*`	All arguments; same as `^-$` or `1-$`
`#`	Current command line up to this point; fairly useless
