Batch move files to new directories

[tabanus]

Any scripting magicians able to help me with this?

I have about 1000 files named so:

x_registration.pdf

Where x is a number that can be anything from 1 to about 110000

These files all sit in one directory. Is it possible to move them automatically to new directories based on the value of x?

For example 987_registration.pdf would be moved to folder /mnt/ftp/clients/987/documents.

Thanks.

Thanks for the quick reply.

When I run the script on some test documents I get the error:

You didn't give us enough information on the file pattern. Ppurka's solution reasonably assumed that the "_" would always be there after the number. Just so I get it straight, what other rules / patterns should I be aware of?

OK, I'm officially retarded.

I forgot to put _docs in the test data file names. It all works perfectly now.

Thanks
