| ksh will allow the seting of vi
so if you use ksh -o vi or have your shell as ksh this will work not in bash
bash shortcuts
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. |
