It is supposed to set environment variables for local user and/or local machine from command line. you might give it a try benjamin -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

The best way to test that is to try actually writing something (which is exactly what "mount" does). Also, there is no SYSTEM account on 9x.

Well, if you really want to check for this you could try comparing the output of "id -u" to 18, the UID of the SYSTEM account. I don't know if the system account's id varies across different versions (eg 98 vs. 2k3), though.

Re: Environment variables & system privilages
Thanks. This works well enough. But I take it there is no universal command to check for system permissions. The procedure is just try a command that needs system privilages and watch the exit status. Also for the benefit of anyone reading this thread - there was an error in my original post. I dropped the "Environment" key from the registry path for setting system environment variables. It should have read. regtool set -s 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\FOO' 'BAR' Jason Igor Pechtchanski wrote: On Sat, 4 Dec 2004, Jason Pearce wrote: I have two seemingly simple questions that I just can't find the answers to.

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 ??
