password in shell file

[Donald Thaler]

when we run a script out of cron no password is required. when we try to run the script from the command line, it asks us for a password. how can i run this shell script and either pass it a password or like cron not ask for the password?

Hi,

Is that cronjob running as root where it does "su - user -c " ?. For root, it won't prompt for the password. For any user other than 'user', it will.

I suppose that you talk about root cron, and that your script contains something like :
su user -c "unix_script arguments"

From root account, no passwd is requied for this command.
But from an other user, from shell, you have to give a passwd.

Can you confirm and/or give an extract from your script shell ?

Can you post script?

Who is running script?

From command line and from cron?

If root - and it's a su to some user - then no password required....

cron execution is based on root user. When you try that script on user then it will be as user one.

You can use r* commands on this.

make .rhosts on user's home directory and allow between the user's to not ask passwd

Example:

between root and test user then,

.rhosts on root user home dir
localhost test

.rhosts on test user home dir
locahost root

It will not ask passwd.

Thanks all. I was logged on as 'oracle' and running a script that had the following entry
'su - oracle -c "u01/scripts/courseTitleCursor.shl" and it would prompt me for a password. if i just run the script "courseTitleCursor.shl" everything seems to be ok.

Thanks again

Hi,

Yep. Even to su to the same login, it will prompt for a password. If you run it as root, it won't.

When u are logged in as oracle, why to again su - oracle ? you can directly execute the script.

if you have cron jobs scheduled for oracle and if you would like oracle's .profile to be sourced before executing the script in cron, then edit the script that is executed by cron and add

. ~oracle/.profile
<script>

This will ensure oracle's .profile is sourced before executing the script.

Don't forget to assign points, if any response help you.

By default,

IF you try to use su from users other than root it will prompt eventhough it is same user.

And try to use the absolute path on the execution on shell script with su. So the problem of passwd promption is on using su for the same user.
