If i for example start top. suspend it with Ctrl+Z, then enter top again the previously started instance will be continued in the foreground. How can i avoid this behaviour and just start a new instance?

You probably want to unset the option AUTO_RESUME:


Treat single word simple commands without redirection as candidates for resumption of an existing job.

Thank you. Thought there might be a command but this is perfect. – H.B. Jul 9 '12 at 14:26
To start a new instance just this time, arrange for some part of the command name to be quoted, e.g. \top or =top. – Gilles Jul 9 '12 at 21:52
@Gilles: Works as well, why not post that as an answer? – H.B. Jul 10 '12 at 0:29
Why not just press 'q' in top to exit, instead of ctrl-z? Strange. – lornix Jul 10 '12 at 9:36
