Hi,
Have you printed the variable $vars::name to be sure it contains what you
think it does?
Also, try the grep command:
open(LINKS, "$statedir/links.dat") or die "Error at LINKS: $!\n"
my @all_matches = grep (/$vars::name/, <LINKS>);
&print_link (@all_matches)
You can use arguments to grep to get inverse lists and such.
