NAME

ops - Perl pragma to restrict unsafe operations when compiling


SYNOPSIS

  perl -Mops=:default ...    # only allow reasonably safe operations
  perl -M-ops=system ...     # disable the 'system' opcode


DESCRIPTION

Since the ops pragma currently has an irreversible global effect, it is only of significant practical use with the -M option on the command line.

perldoc2tree.cgi: /usr/lib/perl5/5.8.8/i386-linux-thread-multi/ops.pm: cannot resolve L in paragraph 15.

See the Opcode module for information about opcodes, optags, opmasks and important information about safety.
