Description Sevan Janiyan 2015-06-13 13:21:31 UTC

Just for the sake of documentation, a cautionary tale of stupidity. It appears that ctrl-c does not behave as intended with /rescue/tcsh. Found out on a system when /rescue/tcsh had been copied to /bin/tcsh after losing /bin/tcsh on a system.
When ctrl-c is pressed, instead of starting a new line, the shell terminates, logging the user out or killing a pane in tmux.

Originally thought to be an issue with Japanese keyboard layout but it should be reproducible with any keyboard.

install -C /rescue/tcsh /bin/tcsh
reboot
login
have one line of input (a single character followed by enter is sufficient)
press ctr-c

You're right, looks like the issue is no longer present. I test on 2 different snapshots from February.
