zcat output

[Me]

How can I get the output from 'zcat' as if I was opening a file? What I
would like to do, is go throug each line return by zcat looking for
specic patterns.

Thanks,
Newbie

open( $z, 'zcat file.gz|' ) or die("Can't open file.gz: $!");
while( <$z> ) {
if( /pattern/ ) {
#do something
}
}

You should also check out the IO::Zlib module on CPAN.
