Yes, that's what you've been told. When you press Ctrl-C, you kill top,
and it stops adding anything to the testcheck file. Until you press
Ctrl-C, top keeps sending output to testcheck.
You may want to use the command
top -b > testcheck &
(the & is essential) which will put top "in the background" and return
control to the shell without killing top.
It would return a line something like
[1] 7665
Later on, you could run
kill 7665
to kill the job, or
fg 1
to return it to the foreground. (CAUTION: obviously, you should use the
numbers that the top ... & command returned!)
(Dapper is a version of the Ubuntu operating system. No-one was
suggesting that it would behave differently to Fedora in this regard).
Hope this helps,
James.
