Luciano,

Was wondering if you could provide some help with the solution you
sent...

[ "$( zcat /folder/pg_backup.$DATE.gzip | head -c1 | wc -c )" -eq 1 ]

First, I can't seem to use zcat, because it likes to add on a ".Z" to
the filename for some reason or another. Also, I find with the
version of 'head' installed on my machine, that -c isn't available,
but instead, -n. I tried changing that and zcat to cat, but was
getting a fail on something that should be valid.

This basically checks to see if the file contains data right?

Thanks man!
