in reply to [SOLVED]: Using glob in file test gives "Use of uninitialized value in -e" warning.

When I enable warnings on the command line, I get warnings :) 
perl -wle 'print -e glob "/abc/def/ghi/test*"'
Use of uninitialized value in -e at -e line 1.
Use of uninitialized value in print at -e line 1.

Here is one way to do what you want: 

if (glob '/abc/def/ghi/test*') {
    # sudo
}
