Appendix J. History Commands
The Bash shell provides command-line tools for editing and
manipulating a user's command history. This
is primarily a convenience, a means of saving keystrokes.
Bash history commands:
history
fc
bash$ history
1 mount /mnt/cdrom
2 cd /mnt/cdrom
3 ls
...
|
Internal variables associated with Bash history commands:
$HISTCMD
$HISTCONTROL
$HISTIGNORE
$HISTFILE
$HISTFILESIZE
$HISTSIZE
$HISTTIMEFORMAT (Bash, ver. 3.0 or later)
!!
!$
!#
!N
!-N
!STRING
!?STRING?
^STRING^string^
Unfortunately, the Bash history tools find no use in scripting.
#!/bin/bash
# history.sh
# Attempt to use 'history' command in a script.
history
# Script produces no output.
# History commands do not work within a script. |
bash$ ./history.sh
(no output)

The Advancing in the
Bash Shell site gives a good introduction to the use of
history commands in Bash.
