Great list, thanks! I have been wanting to delete the word FROM the cursor and learning about alt + d is very helpful.

Moving back or forward one word either with ctrl or alt key and arrow keys is possible, I believe. Should this be added?

command description
alt + f move cursor FORWARD one word (same as alt + right arrow or ctrl + right arrow)
alt + b move cursor BACK one word (same as alt + left arrow or ctrl + left arrow)

Also, it may be helpful to know that shift + ctrl + v pastes from clipboard, and ctrl + y pastes from the cut-buffer, at least in Ubuntu. An example:

  • Create this string: 111 222
  • Highlight 111 and copy it with shift + ctrl + c
  • Place the cursor before 222 and press alt + d to cut it
  • Press shift + ctrl + v and ctrl + y repeatedly, and get 111222111222111222111222

  • Create this string: 111 222
  • Highlight 111 and copy it with ctrl + c (or ctrl + shift + c)
  • Place the cursor before 222 and press alt + d to cut it
  • Press ctrl + v and ctrl + y repeatedly, and get 111222111222111222111222

That behaviour of ctrl + v is not part of bash but of your terminal emulator (Kitty, Alacritty, etc), which captures it and sends your system clipboard contents instead. In pure bash ctrl + v will insert the next "character" you type literally, e.g. ctrl + v followed by backspace inserts ^?, ctrl + v followed by enter inserts ^M.

Similarly for ctrl + c it would send an interrupt, but your emulator captures it first and copies to system clipboard instead.

ctrl + y is bash internal, hence why it comes up in this list. As such, though, it doesn't have access to your system clipboard, it is entirely separate. Hence the behaviour you describe with both clipboards having different contents.

When your emulator is not setup to overwrite ctrl + v you can usually still insert with shift + insert. Many emulators also use ctrl + shift + v or more rarely some combination with space.

Thanks for clarifying. I use Ubuntu, and forgot that I have changed the classic "paste from clipboard" from shift + ctrl +v to ctrl + v, so I have updated my post, to use the standard shortcut (shift + ctrl +v) and also added that this is in Ubuntu. Sorry things got mixed up in my first version.

Ctrl + s isn't reverse search, it's basically for 'pausing the tty'. Ctrl+q is for resuming said pause.

In that case most likely the underlying OS terminal device receives and interprets the shortcut. stty can be used to disable, e.g. stty -ixon. After disabling it on my GNOME terminal, expected history search is started on Ctrl + s .

Hi,
I am very impressed, how did you make the figure?

Great list, I learned a lot.

One thing I would add:
In addition to !n (which runs the history entry n), you can also do !-n which runs the n-th previous command, e.g. !-2 would run the command that preceded your last command.

good to learn that! but isn't pressing up twice easier?

How to discard the current command (not executed yet) and move to a new line without printing anything or deleting the current line?
use case: if I need to copy that line and use it later after executing other commands.

You can discard the current command without executing it and move to a new line by using the keyboard shortcut Ctrl+U. This clears the current line but saves it in a buffer, allowing you to paste it back later with Ctrl+Y.

What I find quite confusing is that CTRL + w and ALT + d are not exact opposites of each other.
CTRL + W will delete a space seperated word like word_num_1 word_num_2, while
ALT + d will only delete until the underscores. I wondering if it is configurable that ALT + d behaves the same as CTRL + W or if there is an inbuilt alternative?
