Too late for "-T" option
(X) The #! line (or local equivalent) in a Perl script contains
+the
-T option, but Perl was not invoked with -T in its command line.
This is an error because, by the time Perl discovers a -T in a
script, it's too late to properly taint everything from the
environment. So Perl gives up.
If the Perl script is being executed as a command using the #!
mechanism (or its local equivalent), this error can usually be f
+ixed
by editing the #! line so that the -T option is a part of Perl's
first argument: e.g. change "perl -n -T" to "perl -T -n".
If the Perl script is being executed as "perl scriptname", then
+the
-T option must appear on the command line: "perl -T scriptname".
