#140 request for feature: handling file lists for input
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!!
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
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.
Oops, should've thought of this earlier:
try renaming book1ch2.lst to book1ch2.m3u then
sox book1ch2.m3u chapter2.wav
Assuming existing m3u support is adequate.
