Suspend and resume output in terminal
03 March 2005
To some people it's obvious but I just learnt this now. It's bugged me several times where I've accidently pressed Ctrl-S and the terminal freezes. I had no idea what to do so I had to close the window with Alt-F4. This is extra annoying if you have a ssh session open.
What Ctrl-S does it that it freezes the output on the terminal. Ctrl-Q resumes it again. I can't think of a real usage for me for this but it's good to know if you accidently "freeze" your terminal.
