How can I stop a running R command in linux other than with Ctrl + C?

Question

I\'m running R in interactive mode under Linux and mistakenly typed in a command that takes forever to run. I usually stop it using Ctrl + C. But it do

I have had the problem you mention. Ctrl + C will work when R is able to realize "Oh, this guy/gal wants me to stop running that particular command." However, often R cannot do that. So you have to run Ctrl + \ (note that it's a backslash, not a forward slash). This tells Linux "Hey, R is not listening to me, can you stop running R?".

Try Ctrl + C first, because if it works you will still have your R session. If it doesn't work, and you do Ctrl + \ you will lose your R session, but at least it stops the process.

If that doesn't work either, then I would suggest a killall R or a kill -9 [PID] where you find the PID by running pus aux.
