== Basics ==

* Use '''up and down arrows''' to recall previous command
* Use '''right and left arrows''' to make changes in current command line
* After one or more letters of a command or filename, hit the '''Tab key''' for command or filename complete; if this is non-unique, hit the Tab key '''a second time''' for possible choices.
* '''!'''gcc will repeat the previous command starting with 'gcc'
* 'gvim '''!$'''' will apply the command 'gvim' to the last argument on the previous command line (in Unix, '$' is a symbol for last row, column or argument depending on the context)

== Other useful methods for editing command line ==

Includes the command line for interactive command based programs such as Splus [in emacs edit mode], R, maple, octave, mysql etc]

Most of these are the same as editing in emacs, so you can check the emacs on-line help for other quick-edit possibilities.

The editing is based on the ctrl-key in combination with another key (usually a meaningful letter for a-z) or the esc-key followed by another key (from a-z)

'''Ctrl keys'''

* ctrl-a: beginning of line
* ctrl-e: end of line
* ctrl-k: delete (kill) remainder of line
* ctrl-u: delete entire command line
* ctrl-w: delete previous word
* ctrl-t: transpose 2 characters
* ctrl-y: yank or recover previous deletion
* ctrl-d: delete character at cursor; note distinction from the backspace key or ctrl-h: delete character before cursor
* ctrl-f: forward one character (needed in 'emacs/Splus -e' because arrows keys don't work)
* ctrl-b: backward one character (same comment as above)

'''Esc combinations'''

* esc-d: delete word
* esc-f: forward a word
* esc-b: backward a word
* esc-t: transpose two adjacent words

Note that some of the Ctrl-key combinations like ctrl-a, ctrl-e, ctrl-k, ctrl-u also may work in entry fields in X applications (an example is the web Location entry box in the netscape browser.
