Please don't top post. I think you've been asked this before.

Tha's because as a one liner it doesn't use parentheses. And also
becuase YESSSSS isn't a string, it's a constant. Do you have warnings
turned on? warnings and strict would catch these sorts of things.
print "Yes" if $1; # or
if ($1) {print "Yes"}
Your choice.

I think we need a clearer description of what you want to do here. At
least I do. will your last line have "original.1"? Or will it have
something else? i don't think anyone knows what "the "end of
original.1" means. "original.1" is a string, and the current code
matches that string. If you need to match the end of the string, use
'/original\.1$/'.
I think, though that you mean the end of some block of lines in your data
file.
It looks to me like you want something along the lines of :
while(<>) {
if (/allsets/ .. /original\.1/) {
print;
} elsif (/media/ .. /Total/) {
print;
}
}

BOTTOM POST
I got it working and the code I am using is now
open (ARC, "archiver -lv |") or die $!;
my $flag=0;
foreach (<ARC>)
{
if (/(?i)allsets/)
{
$flag=1;
}
if ($flag==1)
{
print $_;
}
}
as opposed to
if (/allsets/ .. /original1.1/ )
because I needed the data after original1.1.
thank you
