Hello NG,

Can anybody tell me how to leave a process running after logging off? I
have tried postfixing with '&', which leaves my terminal clear to do
other stuff, but as soon as I close my terminal window, the process
terminates (I can see this by watching the running processes with 'top'
in another terminal window). How do I keep a process running after
logging off?

Thanks in advance!

Best,

M.L.

You need to use the nohup command:

	$ nohup my_command &

Closing a terminal (or logginh out) causes a NOHUP signal to be sent
to the appropriate processes.  The nohup command circumvents this.

Hi!

Thanks! I'll give it a try. Also thanks for your answer a few days ago
in my other thread (foce cp to overwrite existing files) - I just
noticed it now :)

Best,

M.L.

Use GNU screen.

As other said, 'nohup <command> &' will work but most of the times,
some times depending on the terminal, connection type 'ssh, telnet, r*'
it may not work. In general, I use
'at now' command which always works on any unix platform.

On Linux, in C, it's possible to call daemon() to detach the prog... Is 
it possible with Solaris ?

My (little) research was unsuccessful

Thanks in advance...

With the benefit of having a email when/if it terminates!

Good alternative, but can you give an example of when nohup fails? I've
never seen it not work, that I can remember.

Colin

I found that it failed with vncserver
