Re: how to name an archive

*** It's surely the backticks.  When the shell sees backticks, it runs 
the command that's inside the backticks, and
substitutes the OUTPUT of the command.

  So for example if I say "echo ls", I get "ls".  If OTOH I say "echo 
`ls` ( with backticks ),
I get a list of files.

   Even more interesting - if I say "cat `ls`", I get the content of all 
the files.
In general  - single quotes mean - get me everthing inside the single 
quotes VERBATIM - don't interpret special chars.
            - double quotes mean - get me everything inside the quotes, 
but do interpret special chars and do variable substitution
            - backquotes means = run the program inside the backquotes 
and get me its output
