I had two files whose names started with amanda in that directory.  I would 
have assumed it would expand the src pattern of "amanda*" to match only those 
two files.  And the rest of the files in /home/me, weren't bothered.  No 
damages to the src directory at all other than removing the files.

If it expanded that * to include the whole thing, it should have moved the 
whole thing.  It didn't.  In past experience, the target path spec's /* has 
always served as just a place holder for the filenames actually selected by 
the amanda* in the src spec.  That is not what it did this time.  This time 
it created a tmp/ directory in /home/amanda, moved the whole amanda tree to 
the tmp directory, including the two files I actually asked it to move from 
/home/me/Download.  No loss, but a very surprised veteran linux user.

Someplace, the plans of mice and men have definitely gone aglay here, so I've 
included address@hidden

Cheers, Gene
