Shell Programming and Scripting

Hi
I am trying to write a login script for network based clients (OSX) that looks up local accounts eg admin, root, etc and exits the script so that it doesn't apply to them. Then for everyone else I make folders eg movies, music, etc that are placed in local harddrive rather than the default place on the server harddrive.
At the moment this script creates the desired effect for the root user no matter who logs in. If I remove the first couple of lines that try to sort out the admin users it works for everyone who logs in. However I want it to work for everyone except root and local users.
ie
#!/bin/sh
#
CURRUSER=`whoami`

ADMINGROUP=`groups | grep admin`
if [ `expr "$ADMINGROUP" != ""` = 1 ]
then
exit 1
fi

mkdir -p /Users/Shared/$CURRUSER/Movies
mkdir -p /Users/Shared/$CURRUSER/Music
mkdir -p /Users/Shared/$CURRUSER/Pictures
mkdir -p /Users/Shared/$CURRUSER/Music/iTunes
mkdir -p /Users/Shared/$CURRUSER/Music/GarageBand
mkdir -p /Users/Shared/$CURRUSER/Pictures/iPhoto Library


rm -R ~/Movies
rm -R ~/Music
rm -R ~/Pictures

ln -s /Users/Shared/$CURRUSER/Movies ~/Movies
ln -s /Users/Shared/$CURRUSER/Music ~/Music
ln -s /Users/Shared/$CURRUSER/Pictures ~/Pictures


Hope someone can help.

I couldn't get your if statement to work (but that could be due to the OS I'm running - can't tell since you didn't post yours).

Try this instead:

Code:

ADMINGROUP=`groups | egrep -c admin`

if [ "$ADMINGROUP" > 0 ]
   then
      exit 1
fi

OSX 10.3

Thanks I'll give it a try.

Hi I tried it and it makes sense but the script does not quite work yet , a bit of progress has been made at this link.

http://discussions.info.apple.com/we...736.689d315b/3

My script currently looks like this

#!/bin/sh
#
CURRUSER=`whoami`

ADMINGROUP=`groups | egrep -c admin`

if [ "$ADMINGROUP" > 0 ]
then
exit 1
fi

mkdir -p /Users/Shared/$CURRUSER
mkdir -p /Users/Shared/$CURRUSER/Movies
mkdir -p /Users/Shared/$CURRUSER/Music
mkdir -p /Users/Shared/$CURRUSER/Music/iTunes
mkdir -p /Users/Shared/$CURRUSER/Music/GarageBand



rm -R ~/Movies
rm -R ~/Music


ln -s /Users/Shared/$CURRUSER/Movies ~/Movies
ln -s /Users/Shared/$CURRUSER/Music ~/Music


I will add the chown part but it still needs something to create the $CURRUSER directories rather than roots . This last sentence makes sense if you read the input at the link above.

Add logic such as a prompt to actually set the value of CURRUSER to the ID of the person who will own the directories. Since you are running as root, then you could issue the command su $CURRUSER without the need to supply a password.

Would I do that just before I make the directories in the script and I am not quite sure how.
I guess I don't understand how your trying to use su.
Could you give an example in my script how you might do it.
Thanks

#I had thought for some reason that the script was being
#executed by root and not the everyday user

Are you saying it works for root but not others? Are you getting any permission errors, unable to create directory errors?

How are you executing the script? Does root own the script and do you have the SUID permission bit set? This would allow anyone who executes the script to run the script as if they were root (security issues with SUID's). What permissions are set for this script?
