history ( -h | --help )
history is used to search, delete, and otherwise manipulate the history of
The following operations (sub-commands) are available:
- search returns history items matching the search string. If no search
string is provided it returns all history items. This is the default
operation if no other operation is specified. You only have to explicitly
say history search if you wish to search for one of the subcommands. The
--contains search option will be used if you don't specify a different
search option. Entries are ordered newest to oldest unless you use the
--reverse flag. If stdout is attached to a tty the output will be piped
through your pager by the history function. The history builtin simply
writes the results to stdout.
- delete deletes history items. Without the --prefix or --contains options,
the exact match of the specified text will be deleted. If you don't
specify --exact a prompt will be displayed before any items are deleted
asking you which entries are to be deleted. You can enter the word 'all'
to delete all matching entries. You can enter a single ID (the number in
square brackets) to delete just that single entry. You can enter more than
one ID separated by a space to delete multiple entries. Just press [enter]
to not delete anything. Note that the interactive delete behavior is a
feature of the history function. The history builtin only supports --exact
- merge immediately incorporates history changes from other sessions.
Ordinarily fish ignores history changes from sessions started after the
current one. This command applies those changes immediately.
- save immediately writes all changes to the history file. The shell
automatically saves the history file; this option is provided for internal
use and should not normally need to be used by the user.
- clear clears the history file. A prompt is displayed before the history is
erased asking you to confirm you really want to clear all history unless
builtin history is used.
The following options are available:
These flags can appear before or immediately after one of the sub-commands
- -C or --case-sensitive does a case-sensitive search. The default is
case-insensitive. Note that prior to fish 2.4.0 the default was
- -c or --contains searches or deletes items in the history that contain the
specified text string. This is the default for the --search flag. This is
not currently supported by the delete subcommand.
- -e or --exact searches or deletes items in the history that exactly match
the specified text string. This is the default for the delete subcommand.
Note that the match is case-insensitive by default. If you really want an
exact match, including letter case, you must use the -C or
- -p or --prefix searches or deletes items in the history that begin with
the specified text string. This is not currently supported by the --delete
- -t or --show-time prepends each history entry with the date and time the
entry was recorded. By default it uses the strftime format # cn. You can
specify another format; e.g., --show-time='%Y-%m-%d %H:%M:%S ' or
--show-time='%a%I%p'. The short option, -t, doesn't accept a strftime
format string; it only uses the default format. Any strftime format is
allowed, including s to get the raw UNIX seconds since the epoch.
- -z or --null causes history entries written by the search operations to be
terminated by a NUL character rather than a newline. This allows the
output to be processed by read -z to correctly handle multiline history
- -<number> -n <number> or --max=<number> limits the
matched history items to the first 'n' matching entries. This is only
valid for history search.
- -R or --reverse causes the history search results to be ordered oldest to
newest. Which is the order used by most shells. The default is newest to
- -h or --help display help for this command.
Deletes all history items
history search --contains 'foo'
Outputs a list of all previous commands containing the string 'foo'.
history delete --prefix 'foo'
Interactively deletes commands which start with 'foo' from the history.
You can select more than one entry by entering their IDs separated by a space.
By default interactive commands are logged to $XDG_DATA_HOME/fish/fish_history
You can set the fish_history variable to another name for the current shell
session. The default value (when the variable is unset) is fish which
corresponds to $XDG_DATA_HOME/fish/fish_history. If you set it to e.g. fun,
the history would be written to $XDG_DATA_HOME/fish/fun_history. An empty
string means history will not be stored at all. This is similar to the private
session features in web browsers.
You can change fish_history at any time (by using set -x fish_history
'session_name') and it will take effect right away. If you set it to
'default', it will use the default session name (which is 'fish').
Other shells such as bash and zsh use a variable named HISTFILE for a similar
purpose. Fish uses a different name to avoid conflicts and signal that the
behavior is different (session name instead of a file path). Also, if you set
the var to anything other than fish or default it will inhibit importing the
bash history. That's because the most common use case for this feature is to
avoid leaking private or sensitive history when giving a presentation.
If you specify both --prefix and --contains the last flag seen is used.
Note that for backwards compatibility each subcommand can also be specified as a
long option. For example, rather than history search you can type history
--search. Those long options are deprecated and will be removed in a future
