Mac Forum / Programming / Perl / January 2006Finding the current user
I know I can get this with `whoami`, but I was wondering if there was a "Perl" way to find the user who executed the script. I basically want to make it so my script is executable by normal users, but prints an error if it is not only the root user. -- Thanks, James Reynolds University of Utah Student Computing Labs james@scl.utah.edu 801-585-9811 > I know I can get this with `whoami`, but I was wondering if there > was a "Perl" way to find the user who executed the script.

If you need more than the numeric user ID, have a look at: perldoc getpwnam perldoc User::pwent sherm-- Cocoa programming in Perl: http://camelbones.sourceforge.net Hire me!
