Linux – How to prevent or interrupt accidental copy/paste in the terminal

bashcopy/pastelinuxterminalurxvt

When I paste into the terminal, sometimes what is in the clipboard is not what I expected. Specifically, it is sometimes pages and pages of text from a website.

When this happens, the terminal goes crazy, blinking rapidly and spitting out command not found as fast as it can.

I am afraid that someday the text will contain something like rm -rf /.

What is the best way to:

  • act when I make such a mistake?
  • prevent such a mistake from occurring?

For details, I use bash in GNU screen windows in a urxvt terminal on Linux.

The usual Ctrl-C or Ctrl-Z have no effect in my experience.

To safely paste, you could invoke a text editor in bash using CTRL + X / E. The shell builtin fc will bring up an editor with the last command.

Short of killing the shell/terminal, I am not sure if there is any way to kill something after you have pasted something in, and it has gone wrong.
