Ctrl+ v : If the next input is also a control sequence, type it literally (e.Ctrl+ u : Clears the line content before the cursor and copies it into the clipboard.Ctrl+ t : Transpose the previous two characters.If you changed that XOFF setting, use Ctrl+ q to return. Ctrl+ s : Go back to the next more recent command of the reverse search (beware to not execute it from a terminal because this command also launches its XOFF).A second Ctrl+ r recalls the next anterior command that corresponds to the search Ctrl+ r : (reverse search) recalls the last command including the specified characters.Ctrl+ p : ( previous) recalls the prior 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+ n : ( next) recalls the next command (equivalent to the key ↓).Ctrl+ l : Clears the screen content (equivalent to the command clear).Ctrl+ k : Clears the line content after the cursor and copies it into the clipboard.Ctrl+ h : Deletes the previous character (same as backspace).Ctrl+ g : Abort the reverse search and restore the original line.Ctrl+ f : Moves the cursor forward one character (equivalent to the key →).Ctrl+ e : ( end) moves the cursor to the line end (equivalent to the key End).If there is text on the current line, deletes the current character (then equivalent to the key Delete).(Only if there is no text on the current line) Sends an EOF marker, which (unless disabled by an option) closes the current shell (equivalent to the command exit).Ctrl+ c : Sends the signal SIGINT via pseudoterminal to the current task, which aborts and closes it.Ctrl+ b : Moves the cursor back one character (equivalent to the key ←).Ctrl+ a : Moves the cursor to the line start (equivalent to the key Home).Tab ↹ : Autocompletes from the cursor position.For example, pressing Alt+ f in Xfce's terminal emulator window does not move the cursor forward one word, but activates "File" in the menu of the terminal window, unless that is disabled in the emulator's settings.

See Editor war § Comparison.Įmacs editing mode key bindings are taken from the text editor Emacs. Readline supports both Emacs and vi editing modes, which determine how keyboard input is interpreted as editor commands. As a cross-platform library, readline allows applications on various systems to exhibit identical line-editing behavior. It allows users to move the text cursor, search the command history, control a kill ring (a more flexible version of a copy/paste clipboard) and use tab completion on a text terminal. It is currently maintained by Chet Ramey as part of the GNU Project. GNU Readline is a software library that provides in-line editing and history capabilities for interactive programs with a command-line interface, such as Bash.
