Bash provides two builtin commands that allow you to 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:fc [-e ename] [-nlr] [first] [last]
fc -s [pat=rep] [command]
${FCEDIT:-${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 Aliases).
history
history [-c] [n] history [-anrw] [filename] history -ps argDisplay the history list with line numbers. Lines prefixed with with a `*' have been modified. An argument of n says to list only the last n lines. Options, if supplied, have the following meanings:
-w
-r
-a
-n
-c
-s
-p
HISTFILE
variable is used.
