Top Forums Shell Programming and Scripting how to run script? call other script? su to another user? make a cron? Post 302315448 by instant000 on Tuesday 12th of May 2009 10:35:09 AM

Good morning. I have tried further, but am still unsuccessful.

The echo works, but it does not execute as expected.

From what I have read on the hp.com forums, this problem could be related to the .profile of the users that I am calling to execute the commands.

http://forums13.itrc.hp.com/service/forums/questionanswer.do?admit=109447627+1242136488365+28353475&threadId=38292

According to what I have read, this could be due to the fact that the user .profile is set up to load a certain user environment, but, I'm not understanding what they mean by changing this environment.

But, I did get the ttytype error that they are talking about "not a typewriter" or something to that effect during my experiments this morning.

I have attempted
su - usera -c commanda
su - userb -c commandb
su - userc -c commandc
what I get is that it appears to logon to each user's login environment (profile, as it were) but it only appears to actually run the command one time, at the very end.
At command prompt, I type it in this way (but of course, I would not be here, unless I wanted to script this.)
I tried a do loop, but it failed.

I tried concatenating scripts with an &, and they run, but I need the su portion, in order to have the permissions on the created file work, as the apparent usera, userb, userc need some perms on the files created as a result of running the script.
Example:
commanda& commandb & commandc
This works, but there is a file(s) created, and it is under "root" and I need the files created under usera, userb, userc, respectively. I saw something about chmod 4700 in the hp.com forums, but that made no sense to me, as I know of only three digits for chmod, so the fourth digit confuses me! What is the purpose of the 4700?

Once I had attempted this, the unix admin had to go back and delete the files wherever they were creted. (He was familiar with this problem, as he had dealt with it before.)

I also tried this:
creating three separate files
filea:
su - usera
commanda
exit
fileb:
su - userb
comamndb
exit
filec:
su - userc
commandc
exit

And concatenating them together on the command line:

filea & fileb & filec
and that didn't work, it appeared to log on to each user profile, and then only executed the commands for userc.

So, I'm back where I started, SOL.

queuedefs(4)							   File Formats 						      queuedefs(4)

NAME
queuedefs - queue description file for at, batch, and cron SYNOPSIS
/etc/cron.d/queuedefs DESCRIPTION
The queuedefs file describes the characteristics of the queues managed by cron(1M). Each non-comment line in this file describes one queue. The format of the lines are as follows: q.[njobj][nicen][nwaitw] The fields in this line are: q The name of the queue. a is the default queue for jobs started by at(1); b is the default queue for jobs started by batch (see at(1)); c is the default queue for jobs run from a crontab(1) file. njob The maximum number of jobs that can be run simultaneously in that queue; if more than njob jobs are ready to run, only the first njob jobs will be run, and the others will be run as jobs that are currently running terminate. The default value is 100. nice The nice(1) value to give to all jobs in that queue that are not run with a user ID of super-user. The default value is 2. nwait The number of seconds to wait before rescheduling a job that was deferred because more than njob jobs were running in that job's queue, or because the system-wide limit of jobs executing has been reached. The default value is 60. Lines beginning with # are comments, and are ignored. EXAMPLES
Example 1: A sample file. # # a.4j1n b.2j2n90w This file specifies that the a queue, for at jobs, can have up to 4 jobs running simultaneously; those jobs will be run with a nice value of 1. As no nwait value was given, if a job cannot be run because too many other jobs are running cron will wait 60 seconds before trying again to run it. The b queue, for batch(1) jobs, can have up to 2 jobs running simultaneously; those jobs will be run with a nice(1) value of 2. If a job cannot be run because too many other jobs are running, cron(1M) will wait 90 seconds before trying again to run it. All other queues can have up to 100 jobs running simultaneously; they will be run with a nice value of 2, and if a job cannot be run because too many other jobs are running cron will wait 60 seconds before trying again to run it.
