in reply to Hash/file --> doesn't seem to work

Well, in my case, the file is big and the hash is relatively small...
hence i chose it this way. Is there a better way to do it?
I'm sure there must be, but just that i don't know them :(
I'll try to use seek and get to the beginning of the file
and then post the complete code.
Update:
This did it:

seek(FILE,SEEK_SET,0);

    But this way vou have to read the big file often. As supposed above it would be better, to switch the while loops.

    untested:

    while(<FILE>) { chomp; my ($objid,$other) = split(/\s+/,$_); while(my ($key,$value)= each (%hash_table)) { if($objid =~ /$key/i) { print "$key is present in $objid\n"; } else { next; } } }
