CTRL+Z stops (pauses) a job
CTRL+C terminates a job
with CTRL+C you cannot resume the process but with CTRL+Z the job can be resumed by just entering at the command promt:
fg %1
if you have multiple processes paused then you should do
jobs
to see the output and select the appropriate number to resume e.g.
fg %3
resumes the third job in the list. You can also have jobs running in the background with
bg %n
where n is the job number.
