script problem

[Thomas Kopp]

Moin,
I have made a script to run a software at boot.

I have linked it in /sbin/rc3.d, I have created the config file in /etc/rc.config.d

if I try to run it in a shell, it work.
but ...
if I reboot the server, start and ( I can see it with a ps -ef starting up) and stop without an error or log.

Can you check the script and give some comments.

hi,

I believe you wish to run these with su command. avoid the '-' sign after the su call.

call it in this manner -

su sc ...

instead of

su - sc ...

'-' runs a shell with the environment settings of the particular user. the script will never return until that shell is exited.

A similar question last night... the same problem...

Hi,

I'm sorry but I think that it should work. with 'su - sc' you will set the environment, execute the command and logout. I Think that your problem is perhaps related to some differences in env variables settings (see man su), or some variables not set (like DISPLAY) because when you run it at boot time your process is not attached to any terminal (you can easily find some tests in most .profile files). Try finally to redirect nohup output rather than rc script output (use "nohup $SC_BINPATH/xscmanmx > /tmp/whatishappening 2>&1).

Regards.

Hi,

Good comment to user the redirect of stout to stderr. This makes your output more complete.

I also have an issue with the folowing line :

/usr/bin/su - sc -c "nohup $SC_BINPATH/xscmanmx" & > /dev/null 2>&1

This should be :

/usr/bin/su - sc -c "nohup $SC_BINPATH/xscmanmx >/dev/null 2>&1" &

Whenever su - generates an error, you want to see it !! Whenever your program xscmanx generates one, I assume you don't want to see it.

I would recommend you keep the su -, as in this case your user profile gets loaded which might important path-variables and $home settings.

Good luck.

Thanks David,

looks better now.
What do you think, do I still need the trap command?

Sorry for the misinformation about shell not exiting, and thanks jean for pointing that out.
