Command-line options (switches). Switches in this variable are taken as if they were on every Perl command line. Only the -[CDIMUdmtwW] switches are allowed. When running taint checks (because the program was running setuid or setgid, or the -T switch was used), this variable is ignored. If PERL5OPT begins with -T, tainting will be enabled, and any subsequent options ignored.
