  onintr

  NAME

    onintr - determines how the shell responds to an interrupts

  SYNOPSIS

    onintr [-|label]

  DESCRIPTION

    This command is a C-shell built-in command.

    The onintr(1) command controls the action of the shell on interrupts.
    Without arguments, it restores the default action of the shell on
    interrupts, which is to terminate shell scripts or to return to the
    terminal command input level. With a hyphen (-), it causes all interrupts
    to be ignored. With label, it causes the shell to execute a "goto label"
    when an interrupt is received or a child process terminates because it was
    interrupted.

    The onintr command is ignored if the shell is running detached and in
    system startup files (see FILES in tcsh(1) ), where interrupts are
    disabled anyway.
