Question: Both of these methods seem to be the same. The map method is, of course, shorter...Why doesn't it work is my question.
here is my map strategy:
$MAIL_ROOT = '/var/mail';
my @users = (map s/$MAIL_ROOT// , `find $MAIL_ROOT -type d -maxdepth
+1`);
and here is the foreach that does what I want, I want to do a map instead of this foreach.
my @users = `find $MAIL_ROOT -type d -maxdepth 1`;
foreach (@users) {
chomp;
s/$MAIL_ROOT//;
print $_ . "\n" unless $_ eq '';
}
is there some reason map is not working correctly?
-----------------------------------------------Update --------------------------------------------
What it might be perhaps...
$_ is undefined because its finding $_ for @users on that same line??? Is this my problem?
In other words, we make sure to return $_ and we're in good shape.
-------------------Solution---------------
Ah, I see, I was assigning the value to s/// and mapping incorrectly:
correct way: chomp( my @users = map { s/$MAIL_ROOT//; $_ } `find $MAIL_ROOT -type d
+ -maxdepth 1` );
from jwkrahn is prob the least effort for a fix and the one i went with :)
