Consider the following bash prompt, where ^ denotes the prompt location:

# git commit -am "[bug 123456] Do this and that with the bug"
                               ^

Suppose that I want to commit again to the same bug, with a different commit message. Is there a way to delete the text from the cursor position till the end of line?

For sure. Use Ctrl+K for it.

It depends on whether you are using vi(set -o vi) or emacs(set -o emacs) editing mode within your shell.

By default, your shell generally defaults to emacs editing mode.

  • In emacs mode, deleting to the end of the line can be accomplished by using the command ctrl-k.

  • If, however, you happen to be using vi editing mode in your command shell, the same result can be accomplished by typing Esc(which will place you in command mode) followed by d-$

If you are uncertain as to which editing mode that you are currently using in your shell, enter the command set -o from the command line and you will be able to determine which editing mode that you are currently using:

set -o
...snip...
emacs           on
...snip...
vi              off

Thanks. It seems that I'm using vi, so CTRL+K does the trick. –  Adam Matan Mar 17 '13 at 9:49
    
If you want a mnemonic, the K stands for kill (the line starting from cursor position). –  Gregor Bruns Mar 17 '13 at 13:53

In vi command mode, D works the same as d$ –  glenn jackman Mar 17 '13 at 16:54
    
+1 for actually writing the right answer and explaining that shellopts may change it. –  TC1 Mar 17 '13 at 20:57

In Kubuntu oneiric (konsole), Ctrl+K and ESC Shift+D both work. ESC d deletes some of the line (maybe up to a ';'). (Typing a $ after that just sends the $ to the console.) I've been trying to figure out how to do that for quite awhile. Thanks! –  Joe Mar 20 '13 at 18:56
