in thread Supressing warnings

#!/home/mh/perl512/bin/perl -w warn "Hubba\n"; # script, produces warning

When you run this as "perl -X" you still get the warning - even though -X should disable them.

Is that because -w (from shebang) is "stronger" than -X (from command line)?


The above is crap - sorry.

    I think the reason Morgon says it's crap is because -w has no effect on warn. If you change the test to actually produce a warning, then the -X on the command line is indeed "stronger" than the -w in the shebang, but that's because the -X is always stronger than the -w, even if they swap places, or are both together on the command line or both together in the shebang.
