Bash provides two builtin commands that allow you to manipulate the
history list and history file.
@table @code
@item fc
@btindex fc
@example
@code{fc [-e @var{ename}] [-nlr] [@var{first}] [@var{last}]}
@code{fc -s [@var{pat}=@var{rep}] [@var{command}]}
@end example
Fix Command. In the first form, a range of commands from @var{first} to
@var{last} is selected from the history list. Both @var{first} and
@var{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 @var{last} is not specified it is set to
@var{first}. If @var{first} is not specified it is set to the previous
command for editing and @minus{}16 for listing. If the @samp{-l} flag is
given, the commands are listed on standard output. The @samp{-n} flag
suppresses the command numbers when listing. The @samp{-r} flag
reverses the order of the listing. Otherwise, the editor given by
@var{ename} is invoked on a file containing those commands. If
@var{ename} is not given, the value of the following variable expansion
is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}. This says to use the
value of the @code{FCEDIT} variable if set, or the value of the
@code{EDITOR} variable if that is set, or @code{vi} if neither is set.
When editing is complete, the edited commands are echoed and executed.
In the second form, @var{command} is re-executed after each instance
of @var{pat} in the selected command is replaced by @var{rep}.
A useful alias to use with the @code{fc} command is @code{r='fc -s'}, so
that typing @samp{r cc} runs the last command beginning with @code{cc}
and typing @samp{r} re-executes the last command (@pxref{Aliases}).
@item history
@btindex history
@example
history [-c] [@var{n}]
history [-anrw] [@var{filename}]
history -ps @var{arg}
@end example
Display the history list with line numbers. Lines prefixed with
with a @samp{*} have been modified. An argument of @var{n} says
to list only the last @var{n} lines. Options, if supplied, have
the following meanings:
@table @code
@item -w
Write out the current history to the history file.
@item -r
Read the current history file and append its contents to
the history list.
@item -a
Append the new
history lines (history lines entered since the beginning of the
current Bash session) to the history file.
@item -n
Append the history lines not already read from the history file
to the current history list. These are lines appended to the history
file since the beginning of the current Bash session.
@item -c
Clear the history list. This may be combined
with the other options to replace the history list completely.
@item -s
The @var{arg}s are added to the end of
the history list as a single entry.
@item -p
Perform history substitution on the @var{arg}s and display the result
on the standard output, without storing the results in the history list.
@end table
When the @samp{-w}, @samp{-r}, @samp{-a}, or @samp{-n} option is
used, if @var{filename}
is given, then it is used as the history file. If not, then
the value of the @code{HISTFILE} variable is used.
