ops(3p) Perl Programmers Reference Guide ops(3p)NAMEops - Perl pragma to restrict unsafe operations when compil-
ing
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.
