I don't know if this is the right board to ask

Is there any condition when the following code might fail and/or crash?

Code:

---

$ more filter.pl
#!/usr/bin/perl

my $cont = 0;
while ($line = <STDIN>) {
    if ($line =~ /^ /) {
        next if $cont;
    }
    $cont = 0;
       
    foreach $i (@ARGV) {
        if ($line =~ /^$i:/) {
            $cont = 1;
        }
    }
    if (!$cont) { print $line; }
}

yeah, if you try to compile it as a C/C++ file it will fial, since it isnt C/C++, you should try a perl board for help on that code.

Maybe you should learn how to read. And I quote

Well, I guess the board description kinda fails there a bit xP
But it's meant for technical questions, most in the line of hardware I'd say... But Cprogramming.com is more made for the C languages, except for C# I think...

Most of the requests for a Java board have been referred to the use of the Tech board, IIRC. I don't see a problem with a Perl question here - a lot of C programmers know Perl too. If he's already an active member, he might as well utilize the community.

It's been a long time since I was familiar with Perl, but considering that the only statements inside your loops are simple assignments and explicit conditionals, I think it's a safe bet your code wont fail or crash.

I agree, looks pretty safe. Unless you or the user can find a way to harm your <STDIN> handle from outside of the program, then I don't see anything that could halt this unexpectedly.
