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.
