Rephrasing what ikegami said already:
the output of `unix_tool file_name` is probably _empty_. What if you run this very command in the shell? What if you use the full path to unix_tool inside the backticks, if unix_tool isn't in the current directory? Maybe these questions can help you in tracking the problem down. Update: what if you dump out $var after filling it, like use Data::Dumper; print Dumper( $var ); Altough this sounds improbable, maybe you just falled over some bug, maybe one that appears only within your environment: what Perl do you use, on what OS?
