$ kill %1

[1]- Terminated man cp

$

bash is only asking the job to quit, and sometimes a job will not want to
do so. If the job doesn't terminate, you can add the -KILL5.1 option to
kill to stop asking and start demanding. For example:

$ kill -KILL %1

[1]- Killed man mv

$

The -KILL option forcibly and unconditionally kills off the job.

In technical terms, kill simply sends a signal. By default, it sends a
signal that requests termination (TERM, or signal 15) but you can also
specify a signal, and signal 9 (KILL) is the signal that forces
termination. The command name kill is not necessarily appropriate to the
signal sent; for example, sending the TSTP (terminal stop) signal suspends
the process but allows it to be continued later.

your processes. Look in the right-hand column for the man ls and man mv
commands. man cp won't be there because you killed it. top is showing you
