Hi,

I was converting some *.m4a files to *.mp3 and ended up with files like:
"name.wav.mp3"

i want to rename them from "name.wav.mp3" to "name.mp3"

i created the following (bash-)script:
#!/bin/bash

s=$1
n=${s/$2.$3/$3}

mv -v "$1" "$n"
<END OF SCRIPT>

i can do:
$ script name.wav.mp3 wav mp3
and this will rename my file

but i do not like this 2nd and 3rd parameter, so i want to do:
$ script name.wav.mp3
but how can this be done?

can anyone point me to the right direction?

zmv '(*).wav.mp3' '$1.mp3'

(zmv is a zsh autoloadable function).

The best way to do this, under the following very common assumptions:
1) You've not done this sort of thing before and am not real
comfortable with it (this is why you're asking here).
2) You probably won't be doing this again for quite some time
(i.e., this is a one-off).

is to do it like this:

ls <files> > foo
vi foo

Bring up foo in an editor (usually vi, but use what you are comfortable with) and change every instance of:

name.wav.mp3
to:
mv name.wav.mp3 name.mp3

The advantage here is that you can see onscreen what is happening -
makes for fewer surprises. When you are happy with it, save and exit
your editor, then "source" foo.

Note that if you are using GNU tools, there are some options to the "mv"
command, such as "-v" that should be useful. Note also that if you have
access to the "mmv" command (very useful, BTW), then you can use that
for further safety.

The point to all this is that safety is the important thing, not
elegance or efficiency. Take it from one who knows - who has on
occasion worked up spiffy (but not quite spiffy enough) shell solutions
to this - only to have something go wrong.

I think this is what you want:

#!/bin/bash
mv -v "$1" "${1/.wav/}"

I think this is what you want:

#!/bin/bash
mv -iv "$1" "${1/.wav/}" # "i" = interative if destination exists
