Question

Cygwin’s bash is often preferable to Windows’ cmd command shell, so we use it to set up our environments before spawning a Windows shell. However, halting execution of a running process in this spawned shell with Ctrl-C kills boots the user back to the bash shell.

My attempted workaround:

source setupEnvironment.sh

restartCommand() {
  # Reset trap
  trap restartCommand SIGINT
  echo -e " === Restarting windows cmd prompt\n"
  cmd /k 
}

trap restartCommand SIGINT
echo -e " === Starting windows cmd prompt\n"
cmd /k

This approach only restarts cmd once. Subsequent Ctrl-C’s are not caught. Is there a way to keep restarting the cmd process?

Does it have to be in the same window? If not, I have had much better luck with

cygstart cmd

cmd starts in its own window; and only exit closes that window
