To calculate the SHA-1 sums, display them and make them available for download in a sums.gz file:
<?php echo(`find ./some_directory/ -type f | grep -v sums.gz | xargs sha1sum | gzip -c | tee sums.gz | zcat`); ?>
To check the sums:
<?php echo(`zcat sums.gz | sha1sum -c -`); ?>
Congrats on getting your domain back!
Hope you won’t have to worry about losing any of them for another couple of years.
I don’t know if it’s cos I’m accessing this from a WinCE terminal, but your first code box in this appears to be empty with just a horizontal scroll bar. The oner in the previous entry looks similar except I can see a single import line.
