make problem with su

Hi
Im having a few problems with a make file im writing. I run the make file as root, then i need to change to another user with 'su - user -c', source their .bash_profile and then in the new shell to execute a script as this user. Something like this (except the syntax doesn't work)

su - user -c ". ~/.bash_profile && $(dirpath)test2.sh"

I can't call the script from the .bash_profile either.

Is this possible, and if so how can i do it ?

Thanks

That syntax looks OK to me (maybe I'm just tired). One problem is that the shell may be interpreting $(dirpath) as a shell variable, which probably doesn't exist if it's set by your Makefile. You might do "echo $(dirpath)" in your su command string to verify this (I'm pretty sure this is your problem, but I'm not sure of an elegant way to fix it; depending on another user's shell environment is not really standard practive in any makefile I've seen).

Hi
Thanks for the reply, i changed the script to run a script in that users home dir (doing away with the $dirpath) and it still wouldn't work. Im always dropped in the new shell.

All i want to know how to do is to run a command like 'env -i bash' and then in the nice clean shell to execute another script. This surely is possible with make ?

su - user -c "env -i bash && $(dirpath)test2.sh"

thanks
