Zsh 5.3 under Win7-64
I'm trying to do the following:
mv TSMUXER/*.ac3 TSMUXER/txmuxer.ac3
The problem is the the * is not being expanded. I have no idea why not.
Any tips will be appreciated.

The command line implies you have a .ac3 file already in TSMUXER and want to
rename it to fixed name txmuxer.ac3. A lack of expansion implies there is no
file matching that pattern. You can prefix simple commands with echo to test
their effect. If a pattern is not expanded, use ls to check what exists in the
source directory, and where it differs from your expectation.

Dotfiles .* are hidden by default under most shell expansions unless .* is
explicitly specified or shell specific options are specified: for zsh specify
the D glob qualifier *(D), for bash set shopt -s dotglob.

... or just do: mv TSMUXER/.*.ac3 TSMUXER/tsmuxer.ac3
(Note the . after the / !)
