Precide a bunch of files with a number in a pattern for example to indisperse a podcast backlock with more recent podcasts

i=10;for o in *.mp3; do i=$(printf "%02d" $i); mv $o $i$o; ((i = $i + 2)); done
This command adds the numbers 10, 12, 14 to a bunch of mp3's in the current working directory. You can then run the command replacing the inital i=10 with i=11 to add 11,13,15 in another directory then mv the files together and the first files interweave with the second group of files. I used this to weave a backlog of a podcast with other podcast so I didn't get sick of one while I was catching up. I started at 10 because printf blows up with 0 padded numbers 08 and 09 which kind of makes the printf command redundant as it was used to pad numbers 1 - 9 so they would come first and not get sorted incorrectly

  • This is a quick line to stream in the latest offerings of your favorite netcasts/podcasts. You will need to have a file named netcast.txt in the directory you run this from. This file should have one and only one of your netcast's/podcst's url per line. When run the line grabs the offering on the top of the netcast/podcast stack and end it over , quietly, to vlc. Since I move around computers during the day I wanted an easy way to listen to my daily dose of news and such without having to worry about downloading to whatever machine I am on. This is just a quick grab and stream of whats current. Future plans... have the list of netcasts be read from the web. possibly an rss or such. I use greader so there might be a way to use it as the source so as not to have to muck with multiple lists Show Sample Output


    1
    vlc --one-instance --playlist-enqueue -q $(while read netcast; do wget -q $netcast -O - |grep enclosure | tr '\r' '\n' | tr \' \" | sed -n 's/.*url="\([^"]*\)".*/\1/p'|head -n1; done <netcast.txt)

Did you mean "Precede a bunch of files with a number in a pattern; for example to intersperse a podcast backlog with more recent podcasts"? I'm not having a go at you, it's just so that if someone is searching they can find your command. :)

Looks like you can use arithmetic expansion: i=10;for o in *.mp3; do mv $o $((i+=2))$o; done
