Hello everyone,

Thanks Joseph for helping out with the support of SaraB.  I truly appreciate it.

I suspect the errors we see are caused by the "cut" command.  I have replaced them with their "awk" 
equivalents.

I have created a patch that can be applied to an unmodified sarab.sh from version 0.2.2.  This patch 
also replaces the incorrect $DATE variable with $BASENAME (fixes email reports).  The patch is 
attached to this email.

To apply the patch, copy sarab.patch to the same directory as sarab.sh and run this...

patch sarab.sh sarab.patch

That should update SaraB, and please test it to verify it works.

Thanks,

Tristan Rhodes
