The value of the @env{HISTSIZE} shell variable is used as the number of commands to save in a history list. The text of the last @env{$HISTSIZE} commands (default 500) is saved. The shell stores each command in the history list prior to parameter and variable expansion but after history expansion is performed, subject to the values of the shell variables @env{HISTIGNORE} and @env{HISTCONTROL}. When the shell starts up, the history is initialized from the file named by the @env{HISTFILE} variable (default @file{~/.bash_history}). The file named by the value of @env{HISTFILE} is truncated, if necessary, to contain no more than the number of lines specified by the value of the @env{HISTFILESIZE} variable. When an interactive shell exits, the last @env{$HISTSIZE} lines are copied from the history list to the file named by @env{$HISTFILE}. If the @code{histappend} shell option is set (@pxref{Bash Builtins}), the lines are appended to the history file, otherwise the history file is overwritten. If @env{HISTFILE} is unset, or if the history file is unwritable, the history is not saved. After saving the history, the history file is truncated to contain no more than @env{$HISTFILESIZE} lines. If @env{HISTFILESIZE} is not set, no truncation is performed. If the @env{HISTTIMEFORMAT} is set, the time stamp information associated with each history entry is written to the history file. The builtin command @code{fc} may be used to list or edit and re-execute a portion of the history list. The @code{history} builtin may be used to display or modify the history list and manipulate the history file. When using command-line editing, search commands are available in each editing mode that provide access to the history list (@pxref{Commands For History}). The shell allows control over which commands are saved on the history list. The @env{HISTCONTROL} and @env{HISTIGNORE} variables may be set to cause the shell to save only a subset of the commands entered. The @code{cmdhist} shell option, if enabled, causes the shell to attempt to save each line of a multi-line command in the same history entry, adding semicolons where necessary to preserve syntactic correctness. The @code{lithist} shell option causes the shell to save the command with embedded newlines instead of semicolons. The @code{shopt} builtin is used to set these options. @xref{Bash Builtins}, for a description of @code{shopt}. @node Bash History Builtins @section Bash History Builtins @cindex history builtins Bash provides two builtin commands which 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 @option{-l} flag is given, the commands are listed on standard output. The @option{-n} flag suppresses the command numbers when listing. The @option{-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 @env{FCEDIT} variable if set, or the value of the @env{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 [@var{n}] history -c history -d @var{offset} history [-anrw] [@var{filename}] history -ps @var{arg} @end example With no options, display the history list with line numbers. Lines prefixed with a @samp{*} have been modified. An argument of @var{n} lists only the last @var{n} lines. If the shell variable @env{HISTTIMEFORMAT} is set and not null, it is used as a format string for @var{strftime} to display the time stamp associated with each displayed history entry. No intervening blank is printed between the formatted time stamp and the history line. Options, if supplied, have the following meanings: @table @code @item -c Clear the history list. This may be combined with the other options to replace the history list completely. @item -d @var{offset} Delete the history entry at position @var{offset}. @var{offset} should be specified as it appears when the history is displayed. @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 -r Read the current history file and append its contents to the history list. @item -w Write out the current history to the history file. @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. @item -s The @var{arg}s are added to the end of the history list as a single entry. @end table When any of the @option{-w}, @option{-r}, @option{-a}, or @option{-n} options is used, if @var{filename} is given, then it is used as the history file. If not, then the value of the @env{HISTFILE} variable is used. @end table @end ifset @node History Interaction @section History Expansion @cindex history expansion The History library provides a history expansion feature that is similar to the history expansion provided by @code{csh}. This section describes the syntax used to manipulate the history information. History expansions introduce words from the history list into the input stream, making it easy to repeat commands, insert the arguments to a previous command into the current input line, or fix errors in previous commands quickly. History expansion takes place in two parts. The first is to determine which line from the history list should be used during substitution. The second is to select portions of that line for inclusion into the current one. The line selected from the history is called the @dfn{event}, and the portions of that line that are acted upon are called @dfn{words}. Various @dfn{modifiers} are available to manipulate the selected words. The line is broken into words in the same fashion that Bash does, so that several words surrounded by quotes are considered one word. History expansions are introduced by the appearance of the history expansion character, which is @samp{!} by default. @ifset BashFeatures Only @samp{\} and @samp{'} may be used to escape the history expansion character. @end ifset @ifset BashFeatures Several shell options settable with the @code{shopt} builtin (@pxref{Bash Builtins}) may be used to tailor the behavior of history expansion. If the @code{histverify} shell option is enabled, and Readline is being used, history substitutions are not immediately passed to the shell parser. Instead, the expanded line is reloaded into the Readline editing buffer for further modification. If Readline is being used, and the @code{histreedit} shell option is enabled, a failed history expansion will be reloaded into the Readline editing buffer for correction. The @option{-p} option to the @code{history} builtin command may be used to see what a history expansion will do before using it. The @option{-s} option to the @code{history} builtin may be used to add commands to the end of the history list without actually executing them, so that they are available for subsequent recall. This is most useful in conjunction with Readline. The shell allows control of the various characters used by the history expansion mechanism with the @code{histchars} variable. @end ifset @menu * Event Designators:: How to specify which history line to use. * Word Designators:: Specifying which words are of interest. * Modifiers:: Modifying the results of substitution. @end menu @node Event Designators @subsection Event Designators @cindex event designators An event designator is a reference to a command line entry in the history list. @cindex history events @table @asis @item @code{!} @ifset BashFeatures Start a history substitution, except when followed by a space, tab, the end of the line, @samp{=} or @samp{(} (when the @code{extglob} shell option is enabled using the @code{shopt} builtin). @end ifset @ifclear BashFeatures Start a history substitution, except when followed by a space, tab, the end of the line, or @samp{=}. @end ifclear @item @code{!@var{n}} Refer to command line @var{n}. @item @code{!-@var{n}} Refer to the command @var{n} lines back. @item @code{!!} Refer to the previous command.

The trailing @samp{?} may be omitted if the @var{string} is followed immediately by a newline. @item @code{^@var{string1}^@var{string2}^} Quick Substitution.

Equivalent to @code{!!:s/@var{string1}/@var{string2}/}. @item @code{!#} The entire command line typed so far. @end table @node Word Designators @subsection Word Designators Word designators are used to select desired words from the event. A @samp{:} separates the event specification from the word designator. It may be omitted if the word designator begins with a @samp{^}, @samp{$}, @samp{*}, @samp{-}, or @samp{%}. Words are numbered from the beginning of the line, with the first word being denoted by 0 (zero). Words are inserted into the current line separated by single spaces. @need 0.75 For example, @table @code @item !! designates the preceding command. When you type this, the preceding command is repeated in toto. @item !!:$ designates the last argument of the preceding command. This may be shortened to @code{!$}. @item !fi:2 designates the second argument of the most recent command starting with the letters @code{fi}. @end table @need 0.75 Here are the word designators: @table @code @item 0 (zero) The @code{0}th word. For many applications, this is the command word. @item @var{n} The @var{n}th word. @item ^ The first argument; that is, word 1. @item $ The last argument. @item % The word matched by the most recent @samp{?@var{string}?} search. @item @var{x}-@var{y} A range of words; @samp{-@var{y}} abbreviates @samp{0-@var{y}}. @item * All of the words, except the @code{0}th. This is a synonym for @samp{1-$}. It is not an error to use @samp{*} if there is just one word in the event; the empty string is returned in that case. @item @var{x}* Abbreviates @samp{@var{x}-$} @item @var{x}- Abbreviates @samp{@var{x}-$} like @samp{@var{x}*}, but omits the last word. @end table If a word designator is supplied without an event specification, the previous command is used as the event. @node Modifiers @subsection Modifiers After the optional word designator, you can add a sequence of one or more of the following modifiers, each preceded by a @samp{:}. @table @code @item h Remove a trailing pathname component, leaving only the head. @item t Remove all leading pathname components, leaving the tail. @item r Remove a trailing suffix of the form @samp{.@var{suffix}}, leaving the basename. @item e Remove all but the trailing suffix. @item p Print the new command but do not execute it. @ifset BashFeatures @item q Quote the substituted words, escaping further substitutions. @item x Quote the substituted words as with @samp{q}, but break into words at spaces, tabs, and newlines. @end ifset @item s/@var{old}/@var{new}/ Substitute @var{new} for the first occurrence of @var{old} in the event line. Any delimiter may be used in place of @samp{/}. The delimiter may be quoted in @var{old} and @var{new} with a single backslash. If @samp{&} appears in @var{new}, it is replaced by @var{old}. A single backslash will quote the @samp{&}. The final delimiter is optional if it is the last character on the input line. @item & Repeat the previous substitution. @item g @itemx a Cause changes to be applied over the entire event line. Used in conjunction with @samp{s}, as in @code{gs/@var{old}/@var{new}/}, or with @samp{&}. @item G Apply the following @samp{s} modifier once to each word in the event. @end table
