in reply to having horrors untainting a path string for moving a file

Insecure $ENV{PATH} while running with -T switch at move.cgi line 148

This error message is trying to tell you to tighten down the $PATH environment setting. What I do is set $ENV{PATH} to '' (clear it) and use a known _absolute_ path for every external program being executed. /bin/mv, /bin/rm, etc. Taint is trying to protect you from being easy prey for a trojan horse attack.
