Or even quicker, you can type ' f2r5', where ' f2' moves the cursor right to next occurrence of character ' 2' and ' r5' replaces the character under the cursor with character ' 5'. To do this, you can type ' cw' which means 'change word' and just type out ' arg5': Suppose you wanted to change arg2 to arg5: Now, enter insert mode by hitting ' i' and type ' arg5 ' Hit ' ESC' to switch to command mode and press ' 3' followed by ' B':Īlternatively you could have hit ' B' three times: ' BBB'. $ echo arg1 (want to insert arg5 here) arg2 arg3 arg4
Suppose you have typed a command with a few arguments and want to insert another argument before an argument which is three words backward. The example will be performed on this command: Once you have changed the readline editing mode to vi (by typing set -o vi), you will be working in insert mode. Let ' ' be the position of cursor in insert mode in all the examples and ' ' be the position of cursor in command mode. Here are a few examples with screenshots to illustrate the vi editing mode. In insert mode everything you type gets output to the terminal, but in the command mode the keys are used for various commands. The editing happens in two modes - command mode and insert mode. If you are used to a vi text editor you will feel yourself at home. In your bash shell (to switch back to emacs editing mode, type set -o emacs). You may inspect your current keyboard mappings with bash's built in bind command:Ībort can be found on "\C-g", "\C-x\C-g", "\M-\C-g".Īccept-line can be found on "\C-j", "\C-m".Īlias-expand-line is not bound to any keys The difference between the two modes is what command each key combination (or key) gets bound to.
This time I am going to introduce you to bash's vi editing mode and give out a detailed cheat sheet with the default keyboard mappings for this mode.
Emacs editing mode is the default and I already wrote an article and created a cheat sheet for this mode. Bash provides two modes for command line editing - emacs and vi.
