The history command works with the command history list. When the command is issued with no options, it prints the history list. Users can supply options and arguments to the command to manipulate the display of the history list and its entries. The operation of the history command can also be influenced by a shell's environment variables. For ...
Ctrl+l : Clears the screen content (equivalent to the command clear). Ctrl+n : recalls the next command (equivalent to the key ↓). Ctrl+o : Executes the found command from history, and fetch the next line relative to the current line from the history for editing. Ctrl+p : recalls the prior command (equivalent to the key ↑).
Command history is a feature in many operating system shells, computer algebra programs, and other software that allows the user to recall, edit and rerun previous commands. Command line history was added to Unix in Bill Joy 's C shell of 1978; Joy took inspiration from an earlier implementation in Interlisp . [ 1 ]
The license was GPL-1.0-or-later. "In addition to supporting backward-compatibility for scripting, Bash has incorporated features from the Korn and C shells. You'll find command history, command-line editing, a directory stack (pushd and popd), many useful environment variables, command completion, and more."
Search+V: Select all in focused control or window Ctrl+A: ⌘ Cmd+A: Ctrl+A: Ctrl+x, then h: ggVG, unlikely ever needed as most commands take an optional range parameter. % means "all in focused windows" here so e.g. to copy all the text, use:%y: Ctrl+A: Cycle through installed keyboard languages / input methods
A command-line interpreter may offer a history function, so that the user can recall earlier commands issued to the system and repeat them, possibly with some editing. Since all commands to the operating system had to be typed by the user, short command names and compact systems for representing program options were common.
Support for command history means that a user can recall a previous command into the command-line editor and edit it before issuing the potentially modified command. Shells that support completion may also be able to directly complete the command from the command history given a partial/initial part of the previous command.
This functions similarly to Bash's Ctrl+R history search, but is always on, giving the user continuous feedback while typing commands. Fish also includes feature-rich tab completion, with support for expanding file paths (with wildcards and brace expansion), environment variables, and command-specific completions.
