An ipfs replacement for all those bullshit puush/imgur/dropbox/pastebin scripts that break after a few months. Keeps a local log of uploads to make it easier to find them later:

Guess I should explain a little:
-ffmpeg-capture: just click on a window and it starts recording
-flac-to-webm.sh: be careful, the webm produced are special. They can't be seeked and start playing only after full buffering. Minimal size, though.
-music-convert.sh: recursively convert a folder
-zero-pad.sh: pretty explicit (I hope).

Quote your variables faggots.

Poor man's `sponge' (moreutils). A tool that soaks up standard input, which allows reading and writing from/to the same like this:
uniq something.txt | schwamm something.txt

schwamm() { if [ ${#} -eq 1 ]; then printf -- '%s\n' "$(cat /dev/stdin)" >| "${1}" else printf -- '%s\n' "$(cat /dev/stdin)" fi}

With bash you can replace the cat with

You should clean up your code a bit here. Make the referneces to files in their full name (I recommend either using ~/.config/bp/conf or /etc/bp/conf. And put the logs in /var/logs. I tried to clean it up that way but it is not downloading correctly anymore.

Use read to split the line into fields instead of cut.
while read podcast dname

Will not work anymore, the url format changed. For example the url of the OP is /file_store/5d770667648c0

Use: -I '*/src,/file_store'
Use parameter expansion: "${1##*/}"

Guess you're right. That's the only script I didn't make myself, so that explain.

You got a script that convert any file into an mp4, and another that download the same video on YouTube and reverse the process?
