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

Answer 1

Try to use Ctrl + C, pause R with Ctrl + Z, and then unpause R with fg (#job).

I tried the solutions given in previous answers with sending some signals to R with kill, but neither worked. Then I tried the sequence above (Ctrl + C, Ctrl + Z, and fg 1) and it worked. I could continue the R session.

I'm not sure whether it was one of the signals or Ctrl + C that stopped R, but I guess Ctrl + Z was essential here.
