If you by accident press Ctrl-Z on the Linux console, use fg to un-suspend that task

Posted by jpluimers on 2013/07/01

The Linux console has different shortcut keys than many people are used to, so Ctrl-Z is not “undo”, but “suspend”. It sends and returns you to the command prompt.

The easiest way to undo that is to type fg, which brings back the suspended process into the foreground.

A nice post with a bit more background information is Bg, Fg, &, Ctrl-Z – 5 Examples to Manage Unix Background Jobs.
