password in a script

[we2aresame]

I try to write a script which will su to another user to run some commands, how to give the password in the script, thanks.

 

[Chapter11]

Use sudo, it's easier to script for.

There is a way of doing it using "expect" but I'm not familiar with it.

 

[bi]

or, if root is going to execute the script, the syntax is, for example:

su oracle -c "$ORACLE_HOME/bin/dbstart"

(All required paths and environment settings are stated before this line.)

That will work bi, but I wonder about the password in a script as well. Maybe not the best tool for this job, but is it possible without a C program?

 

[bi]

I think the expect route Chapter11 discussed would be a fairly easy way (I've heard -- I've not actually written an expect script). The problem with having a password in any file is the security hole it creates. (And also, I think you would need to have the password for if you use sudo in a script, too.)

we2aresame,bi is obviously correct.
To have a file with the not-encrypted password of another user is as dangerous as suppressing password validation for that user.
sudo is the best thing for executing command like another user .... if you don't wish to write a your own application

I will try sudo, thanks all.
