NetWallah,
I need to copy files from one dir to another. The directories are on two
separate machines across a file share. The files names start with initials
followed by an underscore, then some other characters. I need to put
these files into their respective customer dir.

The customer dir name is the first and last name of the
customer. Example: Michael Jackson. So, in order to copy
a file/s that belong to Michael Jackson I need to match
his initials with his name. That is where the %sequser
hash comes in. It creates a mapping between the initials and name.

My idea is to match the initials of the customer, the values in the hash,
with the initials at the beginning of the file. Then I will know which user
dir to copy the file.

I hope that I have significantly decreased the signal-to-noise ratio.
