I have a quick and dirty script to check the integrity of several data files. I send a list of files as arguments to the script on the command line e.g 

script.perl file1 file2 file3

[download]

An outline of the script is:


while (<>) {
 chomp;

 # ... verify the line ...

 die unless ($verified);

}

[download]

When the program dies, it reports what line it was working on, but not which file the line is contained in. Is there a simple way to extract this information? (I can easily rewrite the script to get a list of filenames and then loop over them, but I was wondering if there is a simpler method.)

Thanks.
