ops(3)


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.

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