Because it is wrong on so many levels. Seriously, assuming
the capitalization of "for" and "if" are typos, you can't just
add a slash "/" wherever you want to and expect perl to know
why. Assuming that trailing slash is also a typo, And you
really meant this ...
for (<FH>)
if (/pattern/) {
split /\=/, $_;
$vg{$_}++
}
}
... then there are still problems. First split() returns
a list of values, but you are not capturing that list. I think
that split() defaults to placing its values in @_, but you are
not accessing that here and it is deprecated.
All the work is being done in "$vg{$_}++" which ignores
the split() and increments the value associated with the key
in $_. That one of those key/value pairs happens to be correct
is just coincidence.
*****************************
Ok guys, yes that was just pseudo code and I was in a hurry to get it
off.
I was being lazy. I have been around awhile, but laziness got the best
of me that time-around.
Now I understand why
for (<FH>)
if (/pattern/) {
split /\=/, $_;
$vg{$_}++
}
}
will not work...aka I was not capturing that list.
Thank you
Derek
