- Subject: Environment variables & system privilages
I have two seemingly simple questions that I just can't find the answers
to. Any assistance would be appreciated
1. What's the "right" way to add add environment variables into the user
and system maps?
Currently I am using regtool to manipulate the registry. For instance to
set an environment variable FOO=BAR I do:
regtool set -s '\HKEY_CURRENT_USER\Environment\FOO' 'BAR'
or
regtool set -s
'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\FOO' 'BAR'
The first form places it in the user's map, the second in the system
map. But will this work across patform? Is there a more preferred method?
2. How can I test whether my script is running with system privilages?
ie I want to write a script that installs a mount and sets and
environment variable. If the script is running with system privilages I
want to make the change system wide. Otherwise, in the user's profile.
#!/bin/sh
if [ ??????? ]
then
# Sytem wide
mount -tfs d:/projects /projects
regtool set -s
'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\FOO' 'BAR'
else
# User ony
mount -tfu d:/projects /projects
regtool set -s '\HKEY_CURRENT_USER\Environment\FOO' 'BAR'
fi
What do I put in place of the ??????
Thanks.
Jason
