Control+T in Terminal shows time snapshot
Authored by: wallybear on Jan 30, '12 02:11:39PM

"detaching from the terminal is like running followed by an & "

No, it isn't.

Ctrl-Z suspends the process. If you want it to continue in background (like when you use &) you must type
"bg" (=background) on the command line, otherwise typing "fg" it will resume in foreground.
It's useful when you launch a process you want to run in background and you forget to put the "&" at the end of the command: just do Ctrl-Z, type "bg" and you are done.

It's a common feature of Linuxes and BSD.
