When concatenating audio files using FFMPEG, you can create the text file listing the audio files with the following command.

printf "file '%s'\n" *.flac > podseglist.txt
ffmpeg -f concat -safe 0 -i podseglist.txt fullpod.flac

If you are using Sox, you can concatenate the files using the following:

sox *.flac fullpod.flac

I covered concatenating audio files using FFMPEG in HPR4608 in my series on Simple Podcasting and these examples are in the show notes as reference for anyone who is interested.

The FFMPEG list file is probably useful for cases where you want to order the files manually rather than using shell globbing order.

(If there turns out to be a double post from me on this subject, the electric power went out just as I was attempting to send it the first time so I didn't think the first one went through.)

Concatenation is frustratingly confusing in ffmpeg, but according to the wiki https://trac.ffmpeg.org/wiki/Concatenate you can just use

ffmpeg -f concat -i listoffilenames.txt output.flac

for some reason it forces you to use a file thats a list of filenames instead of being able to use a glob, but it works pretty ok
