Re: [SoX-users] Mac OS X beginner seeks support for SoX and scripting: splitting 2-channel .wav´s in two .mp3´s

[Jesse R. <jr...@co...>]

Scripting is certainly a fantastic skill, and opens many doors! For
scripting on OS X, I'd recommend "man bash" rather than "man sh", as the
default shell on this platform is bash.

In addition, googling something like "bash tutorial" would likely give you
some more user-friendly resources than the man page.
