Summary: request for feature: handling file lists for input

Initial Comment:
this is a suggested enhancement to sox.

i'd like to be able to provide, as a command line parameter, a file containing a file list to be operated on. for example, the command line syntax might be:

sox @book1ch2.lst chapter2.wav

where the file book1ch2.lst might contain:
disk1track05.wav
disk1track06.wav
disk1track07.wav
disk1track08.wav
disk1track09.wav

it would be intended that this join together the five files specified, in the order specified.

i'm assuming sox doesn't already have a feature to do this that i've missed!!

Message:
the problem is that - in my specific application - i want to:
(a) be able to specify the order that the files are to be operated on -
somewhat important if joining together,
(b) join together a very large number of files, a number whose total name
lengths are likely to exceed the legal command line length under windows
(the o/s i'm using),
(c) NOT have to do multiple smaller join operations, so as to minimize
multiple-handling of files. i'm needing to work with many hundreds of short
files of only 2 or 3 minutes in length, that are assembled into large
'chapters' of up to an hour. as it is, an automated assembly operation of
the collection is likely to take a great many hours.

to fit in with the above, an addition to sox _seems_ to be the most
effective solution.

Message:
This sort of functionality is usually provided by the `shell'.  If you are
using Windows, then you may want to look at `powershell' that comes with
recent versions.

Of course, with the particular example you've given, a simple shell
wildcard '?' or '*' might be enough.

HTH,
Rob
