Hello All,
I have to restart 100's of scripts for at least 20+ users once the server restarts for any reason. I wanted to come up with a single script to trigger of all scripts/programs under all users with just one script (without root privilege).
Is it possible to do so? 
If not, what is the best approach to proceed?
Thanks,
Did you consider the cron / crontab reboot trigger entry? Available in some (linux, FreeBSD), mayhap not all, systems. man crontab :
@RudiC: I do not have access to crontab for all the users. Is it possible to have a single script to call the other scritps for all users? And the sub-scripts would still be running under the appropriate users?
Unless your SysAdmin gives you access to these other user accounts via sudo or some other means I cannot see how you can do this manually, let alone automatically.
We also don't know whether these "script" are shell-scripts, perl-scripts, SQL-scripts or written in some other language.
And we don't know why they have to survive a reboot, or what they do, or can do, to save their status at the time of a reboot.
Can you get your users to, say, rewrite the scripts to save their status to, say, a JSON file on a given signal? Then write a shell-script to be run on shutdown to signal these scripts and save their JSON files somewhere? A second shell-script could then run as root by the system on start-up to start the users scripts with a "continue with the settings from this JSON file" switch.
Even that may not be possible.

Andrew, Thanks for the inputs. I was talking about shell scripts. I have to login manually as USERA, USERB, USERC, ... USERn and run bunch of processes/scripts. For every user, I have a script to check and start up programs if not running.
What I am trying to accomplish here is to avoid the logging in part.! Instead of logging in as n number of users, I just want to login as 1 user (let's say USER) and run 1 script to startup all the scripts that are required for n number of users. Catch is that the script should be executed as the user itself. For example, USERA has usera.sh script to start all the required programs. If I trigger start_all_users.sh from USER, it should trigger usera.sh as USERA.
Will setuid help in this case?
Thanks,
Why, then, you
?
Can you not write this as a script and call it in as the machine starts? You haven't said what OS version you have, so the options a too varied to go through just yet. Do you have access as root / a super-user account or just to all the individual accounts?
If you don't have super-user access, maybe we could write something and ask someone who does to set it up, but we need more information first.
If you can run as the super-user (however we arrange it) then you can do things like su - USERA /path/to/script without it prompting for a password.
What more can you tell us? It's all a bit vague.
