stop - terminates background jobs or processes
stop %job|pid ...
This command is a C-shell built-in command.
The stop(1) command stops the specified jobs or processes that are executing in the background. The job argument can be a number, a string, a null string, %, +, or -, as described in the "Jobs" section of tcsh(1). There is no default job; using stop without an argument does not stop the current job.
