[GRASS-dev] making a GRASS script go superuser and asking you a password before running its command

Hello,

Can anybody help/suggest:

While making a script to install GRASS Extensions, i run into a problem.
GEM needs root access to complete its task.

Is there a way to get the script to ask the user for the password and process
under root permission?

thank you
Yann

Then the user should run the script as root.

Use sudo or "su -c".

Note that if you're relying upon $LD_LIBRARY_PATH to find GRASS
libraries, sudo/su will reset it. You can use $GISBASE/etc/grass-run.sh
to execute a command with LD_LIBRARY_PATH restored.
