如何在bash终端中选择行

Question

Is it possible to select part of a string in the bash terminal and delete it at once, rather than navigating to a point in the command and backspacing it all??

thanks!

Answer 1

I'm not 100% sure I understand your question.

If you are at the interactive command line:

• ctrl-u : Deletes everything to the left of your cursor
• ctrl-k : Deletes everything to the right of your cursor

Answer 2

I'm using emacs bindings and my favourite command line shortcuts, which were not included in the previously linked tutorial, are the following:

^W     - delete last word
meta-b - move cursor back one word
^R     - find a previously used command
!$     - last attribute of the last command
!!     - last command

You can also manipulate the history with regexps, although that could quickly get quite messy. See "man zshexpn" for reference, mostly the same regexp syntax works for bash also.

Example:

1) If you execute the following command:

  echo first second third fourth fifth 

2) Then you could execute the same command and remove "first" by:

  !!:s/first// 

If this was not what you were after, please clarify on your question! :)

Answer 3

See this . Alternatively, set -o vi to have vim-like key bindings.

Note that the list given in the link is not full. You might read man bash for a good reference. Usually, ALT-x might be replaced by ESC, x if you run bash inside a terminal that uses Alt-letter shortcuts for windowing system.
