Hello monks,
I would like your help in understanding the use of map to do hash assignments, ive looked at the faq on here, the cookbook and the camel book but I cant quite work this out..
I have two strings in an array
my @teststr;
my %testhash;
$teststr[0] = "32977186 4 -rw-r--r-- 1 owner mygrp 65 Aug 4
+13:16 /long/path/to/my/file/file1.txt";
$teststr[1] = "32977186 4 -rw-r--r-- 1 owner mygrp 65 Aug 4
+13:16 /long/path/to/my/file/file2.txt";
and I want to put them in the hash to show
file1=>file1.txt
file2=>file2.txt
it works fine if I use foreach:
foreach my $line (@teststr)
{ my ($key, $val);
$val = (split /\//, $line)[-1];
($key = $val) =~ s/\.txt//;
$testhash{$key} = $val;
}
but I think I should be able to use map to do this, I cant seem to account for the changing $_
my %testhash = map {(my $val = (split /\//, $_)[-1]); ((my $key = $va
+l) =~ s/\.txt//);} @teststr;
gives
1 => 1
i think im getting the return value of the s//, so how can I do the split then run the regex on the result?
thanks
