\subsection history-description Description
|
|
|
|
\c history is used to list, search and delete the history of commands used.
|
|
|
|
The following options are available:
|
|
|
|
- \c --save saves all changes in the history file. The shell automatically
|
|
saves the history file; this option is provided for internal use.
|
|
- \c --clear clears the history file. A prompt is displayed before the history
|
|
is erased.
|
|
- \c --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.
|
|
- \c --search returns history items in keeping with the \c --prefix or
|
|
\c --contains options.
|
|
- \c --delete deletes history items.
|
|
- \c --prefix searches or deletes items in the history that begin with the
|
|
specified text string.
|
|
- \c --contains searches or deletes items in the history that contain the
|
|
specified text string.
|
|
|
|
If \c --search is specified without \c --contains or <code>--prefix</code>,
|
|
\c --contains will be assumed.
|
|
|
|
If \c --delete is specified without \c --contains or <code>--prefix</code>,
|
|
only a history item which exactly matches the parameter will be erased. No
|
|
prompt will be given. If \c --delete is specified with either of these
|
|
parameters, an interactive prompt will be displayed before any items are
|
|
deleted.
|
|
|
|
\subsection history-examples Example
|
|
|
|
<code>history --clear</code> deletes all history items
|
|
|
|
<code>history --search --contains "foo"</code> outputs a list of all previous
|
|
commands containing the string "foo".
|
|
|
|
<code>history --delete --prefix "foo"</code> interactively deletes the record
|
|
of previous commands which start with "foo".
