Bash provides two builtin commands which manipulate the history list and history file.
fc
|
Fix Command. In the first form, a range of commands from first to
last is selected from the history list. Both first and
last may be specified as a string (to locate the most recent
command beginning with that string) or as a number (an index into the
history list, where a negative number is used as an offset from the
current command number). If last is not specified it is set to
first. If first is not specified it is set to the previous
command for editing and -16 for listing. If the `-l' flag is
given, the commands are listed on standard output. The `-n' flag
suppresses the command numbers when listing. The `-r' flag
reverses the order of the listing. Otherwise, the editor given by
ename is invoked on a file containing those commands. If
ename is not given, the value of the following variable expansion
is used: ${FCEDIT:-${EDITOR:-vi}}
. This says to use the
value of the FCEDIT
variable if set, or the value of the
EDITOR
variable if that is set, or vi
if neither is set.
When editing is complete, the edited commands are echoed and executed.
In the second form, command is re-executed after each instance of pat in the selected command is replaced by rep.
A useful alias to use with the fc
command is r='fc -s'
, so
that typing `r cc' runs the last command beginning with cc
and typing `r' re-executes the last command (see section 6.6 Aliases).
history
history [n] history -c history -d offset history [-anrw] [filename] history -ps arg |
With no options, display the history list with line numbers. Lines prefixed with a `*' have been modified. An argument of n lists only the last n lines. Options, if supplied, have the following meanings:
-c
-d offset
-a
-n
-r
-w
-p
-s
When any of the `-w', `-r', `-a', or `-n' options is
used, if filename
is given, then it is used as the history file. If not, then
the value of the HISTFILE
variable is used.
