To suspend a foreground process:
find / -name *.c -print find: cannot read /dev/diag ... ^Z + Stopped find / -name *.c -print ps 22926 p9 S 0:03 -Tcsh (Tcsh) 29857 p9 T 0:00 find / -name *.xdh -print 29859 p9 R 0:00 ps mail tony < memo.txt
The user enters a command to find files with the extension .xdh starting at the root directory.
Realising that this process will take a long time to run they stop it while they do something else.
They check to see that the process still exists: it does. They then send some mail to the user tony. Now they can restart the process again in the foreground or run it as a background job.
