Difference between Ctrl C and Ctrl \

Question

What is the difference between Ctrl-C or Ctrl-\ for terminating a process?

They are both similar though.

Can't find any documentation for Ctrl-\.

Answer 1

CtrlC sends SIGINT to the foreground process, Ctrl\ sends SIGQUIT. The default handlers for both of them terminate the process, but the handler for SIGQUIT will also create a core dump (unless core dumps are disabled).

See here for a list of how all the standard termination signals are processed by default.
