The point of -c is to set the euid of the process, that is all :) Anything that is dependent on a particular user's base environment should be specified as opposed to expecting that environment. For example, root's path does not include /usr/local/bin or ~user/bin. If I want to run a program from one of those locations as a user via su in a script, I use su -c "~user/bin/program" You *shouldn't* require access to a specific user's environment for administrative functions, which is all the root account is meant for. Set those environment variables you need within the script. This will prevent them from being exported into root's master environment. -- _ _|_|_ ( ) *Anton Graham /v\ / <[EMAIL PROTECTED]> /( )X (m_m) GPG ID: 18F78541 Penguin Powered!

This is correct behavior. su - is a login shell, which is the only time 's profile is loaded. su -c only executes a command as if it were that user. > This is very annoying, I need to create a script that runs as root > and executes some commands as another user.

A shell cannot be both a login shell and only be passed the single command. Also you're attemting to source .profile from $PWD. if $PWD is not 's $HOME then you aren't sourcing the correct file. > How can I get this fixed ?

I just don't understand why su doesn't load -> the user's profile. What's the point of the -c option if it doesn't load -> the profile with the correct PATH settings, etc. ?!? OK, then try escaping the quotes and the semicolon and any other shell special characters in the original. The point of the -c with or without the user profile, etc., depends on what you are trying to do. You may not want the user profile for some things. You may want some other profile, like that of the user you are suing from. Not being a Microsoft product, Linux is not going to prohibit you from doing something just because the developers can't think of a reason why you would want to do it. The sample I showed above does not load the profile, and works just fine. I didn't load the profile in that one because I didn't need it. -- -- C^2 No windows were crashed in the making of this email.

Re: [expert] su - user -c "command" doesn't load profile
true. However, please note that the sudoers file ships with ALL=(ALL):NOPASSWD as an example. ALL does not mean "all the programs I have defined to be run by people I have given access to." Instead, ALL means "every program on the machine." This can bite you, as it is a silent permission. bug On Sat, 24 Jun 2000, Anton Graham wrote: > Submitted 24-Jun-00 by Lars Nordin: > > Try downloading "sudo" that was the old Linux "su" package > > - it should still be out there. > > > > Actually sudo is far more powerdul in limiting access than su is > because you can define who can use what commands and never give out a > superuser password :)

Try downloading "sudo" that was the old Linux "su" package - it should still be out there.

I just don't understand why su doesn't load the user's profile. What's the point of the -c option if it doesn't load the profile with the correct PATH settings, etc. ?!? Thanks, Jasper

[expert] su - user -c "command" doesn't load profile
Hi, On Mandrake 7.0 when you do a su - -c "command" from the root account, 's profile is not loaded. When you just do a su - , it works OK. This is very annoying, I need to create a script that runs as root and executes some commands as another user. I can't get this to work right now. Even su - -c ". .profile; echo $ORACLE_HOME" doesn't work. How can I get this fixed ? I can't remember having this problem on Red Hat or SuSE. I upgraded to the newest sh-utils, but that didn't help either. Also, su doesn't return the correct errorcode if you use the -c flag, it always returns 0. This works fine on e.g. HP/UX and Sun Solaris. Thanks for the help, Jasper
