Appendix I. 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
$HISTSIZE
!!
!$
!#
!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)
