Re: Running epics in background in linux

[Eric Williams <ECWilliams@lbl.gov>]

Rok,
I don't know if this applies to your hardware setup, but I set our IOC 
to run on one of the virtual terminals on our Linux box.  I did this by 
modifying /etc/inittab by first commenting out the old entry for tty6 
and then adding:

ioc:345:respawn:/bin/su -l bl72 </dev/tty6 >/dev/tty6

bl72 is the account for the IOC, and has a .cshrc file set up in its 
home directory to start the st.cmd file.

If you don't have virtual terminals, you should be able to redirect I/O 
to some other device, a file, or /dev/null.
