Functions: bash mail nohup

Run "ps -x" (process status) in the background every hour (in this example).

The outputs of both "nohup" and "ps -x" are sent to the e-mail (instead of nohup.out and stdout and stderr).

If you like it, replace "ps -x" by the command of your choice, replace 3600 (1 hour) by the period of your choice.

You can run the command in the loop any time by killing the sleep process. For example

ps -x

2925 ? S 0:00.00 sh -c unzip E.zip >/dev/null 2>&1

11288 ? O 0:00.00 unzip E.zip

25428 ? I 0:00.00 sleep 3600

14346 pts/42- I 0:00.01 bash -c while true; do ps -x | mail pascalv; sleep 3600; done

643 pts/66 Ss 0:00.03 -bash

14124 pts/66 O+ 0:00.00 ps -x

kill 25428

After you execute a command (or shell script) in the background using

&, if you logout from the session, the command will get killed. To avoid

that, you should use nohup as shown below.

nohup cat /dev/ttyS0 | tee -a llamadas.db&
nohup df -k | sort -rn 12
nohup ping -i1 www.google.com &
nohup nautilus &
nohup gnome-open . 0</dev/null 1>/dev/null 2>/dev/null&

this will open the current directory in nautilus detached from your terminal.

nohup VBoxHeadless -p 3052 -startvm ServidorProducao &
nohup /bin/sh myscript.sh 1>&2 &>/dev/null 1>&2 &>/dev/null&

This command runs your shell script in the background with no output of any kind, and it will remain running even after you logout.
