Re: Comparing arrays

<i>
while (<INPUT1>)
{
    my $line = $_;
    chomp $line;
    my @words = $line;
}

while (<INPUT2>)
{
    my $line2 = $_;
    chomp $line2;
    my @words2 = $line2;
}
</i>

can be replaced with:

my @words1 = <INPUT1>
my @words2 = <INPUT2>

Coming to matching strings you can use ^(match at beginning) and $(match at end of string) according to requirement. so that partial matching is done.

Can it? `use strict; use warnings; my @words1 = <INPUT1> my @words2 = <INPUT2> __END__ syntax error at G:\x.pl line 5, near "my " Global symbol "@words2" requires explicit package name at G:\x.pl line + 5. Execution of G:\x.pl aborted due to compilation errors.` [download] It's not even complaining about trying to read from unopened filehandles, because the error occurs at compile time - even before perl realizes that the read operation would fail. The solution is obvious - you forgot a semicolon. But even then, will it hold? `use strict; use warnings; open INPUT1, "<", "x.pl"; my @words1 = <INPUT1>; print "<$_>\n" for @words1; __END__ <use strict; > <use warnings; > < > <open INPUT1, "<", "x.pl"; > <my @words1 = <INPUT1>; > <print "<$_>\n" for @words1;>` [download] That doesn't look right. And no wonder - your replacement doesn't do the chomping as it happens in OP's code. Surely you meant `my @words1 = map {chomp; $_} <INPUT1>; my @words2 = map {chomp; $_} <INPUT2>;` [download]	[reply] [d/l] [select]

Btw where is your regular expression(code) to match strings?	[reply]
