fill your mp3 player with a random mix

I have an ancient mp3 player that only holds 512M. This is plenty long enough for my work when set it on shuffle play, but I like to remix the player once a week or so. I have a directory full of rips from somafm (using streamripper), and a few songs I always like to have in the mix. This script includes those I like to keep, and then builds a random list from the rips until I have enough to fill the player. I like arrays, so I used one again here. The script is easily modified, and you may or may not find it useful, but here it is anyway. Use any ideas you like, leave what you don't.
Code: Select all
#!/bin/bash
# copy music from src to dest
# stop when dest is full enough for mp3 player
SRC="/media/shared/somafm" # where to get the songs
DEST="/media/shared/music-list" # where to put the random mix
KEEP="/media/shared/somafm/keep/*.mp3" # songs you always want in the mix
MAX_SIZE=450000 # how big is the mix?
rm $DEST/* # delete the old mix
cp $KEEP $DEST # copy songs to keep
alist=( $(shuf -e $SRC/*.mp3) ) # BAD IDEA if file names contain spaces
n=0
for song in ${alist[*]}; do
let n+=1
cp "$song" $DEST
size=$(du $DEST | awk '{print $1}')
echo $n $size $song
[[ $size -gt $MAX_SIZE ]] && break # stop when it's big enough
done
WARNING! Using "shuf" (or "ls") to fill an array like this is a BAD IDEA if any of the files in the music directory contain spaces. You will see a bunch of failed copies as the script tries to copy files that do not exist, and you will hear me asking why you have file names with spaces in them.

Well, believe you me, I find it very useful. I got an mp3 reader I use in my car (with one of
these toys), and I'll use this to update it. Thanks for sharing this script.

really nice pids, might adapt it for a mp3 CD player... Love the fill until full Idea!

You're both very welcome! GekkoP, I have a similar adapter for my old car. Wux, it should be easy to modify the script to fill mp3 CDs. I added the script to my github:

cheers Pids, will play when less inebriated 8)
I had tape converters, but they were pretty hit and miss, I treated myself to a cheap Sony CD with front aux in.

Damn, I have an oooold 512 MB mp3 player too somewhere, one of those that you can pull apart and it turns into a USB stick. If I can find it, I'm definitely using this script.

nice, thanks for sharing. And if it is not the old mp3 player, it can be the (smart)phone :)

Just awesome. I have an old mp3 player I still use and it has 2 GB. Let me try that script the next time I travel.

Pidsley, this was a great idea! One of those
why didn't I think of that? moments.
I have an old 500MB Ipod shuffle I use in the car for which this will be perfect.
I had to hack at your code a bit, though, to fit my purposes.
My music is a big rambling directory tree full of stuff from all kinds of sources with all kinds of naming schemes, and yes many of the filenames have spaces. ..
So, I brought in "find" to get files out of the darkest corners, and to cope with those spaces used 'find
stuff -print0 | xargs -0 shuf -e' to get the shuffled list, then the bash builtin "mapfile" (thanks to Dr. Xaos for that tip) to put that in an array. Spaces in filenames are OK, but names containing linebreaks will still mess it up. Added a bit of quoting too.
I don't know if your "du" is different but I need the -c option to get the total space used, combined with a filter in awk: du -c "$DEST" | awk '/total/{print $1}'
Otherwise your script is exactly the same and in a few seconds went through 15GB to give me a directory with 450MB of nicely random music. (with spaces in some filenames)
fwiw:
Code: Select all
#!/bin/bash
# copy music from src to dest
# stop when dest is full enough for mp3 player
SRC="$HOME/music" # where to get the random mix
DEST="$HOME/for_stick" # where to put the random mix
KEEP=("$HOME/music/keep"/*) # songs you always want in the mix
MAX_SIZE=450000 # how big is the mix?
rm $DEST/*.mp3 # delete the old mix
cp "${KEEP[@]}" "$DEST" # music i always want in the mix
mapfile -t alist < <(find -L "$SRC" -type f -name '*.mp3' -print0 | xargs -0 shuf -e)
n=0
for song in "${alist[@]}"; do
let n+=1
cp "$song" "$DEST"
size=$(du -c "$DEST" | awk '/total/{print $1}')
echo $n $size $song
[[ $size -gt $MAX_SIZE ]] && break # stop when it's big enough
done
terminal:

^ spaces in filenames on Linux still? you are such a heretic John! use my fclean-script (it is out there, somewhere) to clean up those damn spaces, and make all the shit lowercase in the process. much nicer ;)

Yeh, spaces and odd characters (except /) are all allowed in Unix so I feel we should just cope with them instead of getting puritanical about it. I don't go out of my way to put spaces in the names of files I make myself, and also dislike upper-case, but in albums of music the directory name is often displayed by the player somewhere so there's nothing wrong with a directory called "Feats don't fail me now". Then, in stuff that comes from elsewhere names could be any way you can think of, and I'd just as soon spend a few minutes making sure my script can deal with it than go through all those names sanitizing them.

^ i must say, i am quite a purist when it comes to filenames. plus, remember my id3kill script? i don't jive with the whole 'the player will display the name from the tag' - NO. filename.must.be.proper.
but that is just me :)

Really enjoying the random mixes. Hearing music I didn't even know was there, and other stuff sounds quite new taken out of its usual context.

warning: Unix filenames usually don't contain slashes (though pathnames do).
Pidsley's script is working on a correctly set up UNIXoid system, so any removal of spaces and slashes is usually only needed on a system that is owned and used by a dabbler.

...sigh...
What if the files came from elsewhere originally, like out of an rar archive? Are we obliged to sanitize them before putting in our music directory?
Solid systems shouldn't break over something like spaces or linebreaks. (Of course on Unix forward slashes in filenames are not allowed.)

I found myself dealing with spaces so often when working with random sources as to make an option for my killxtools to automagically fix them, because they're disgusting.
johnraff wrote:Are we obliged to sanitize them before putting in our music directory?
As opposed to writing a script, which is essentially JUST a shortcut way to remove a few steps from something that we would do often, that must always include checks for edge cases? Sure, sanitize file names.
I can almost assure you that Pidsley does not give a fuck if anyone else ever uses his script, and that he probably doesn't have spaces in his music file names. Thus, if you do, then do whatever you see necessary to fix it and roll on.
If this script was intended for redistribution or production, it might be different, but this is just a 'Hey guys, check out this
method that I use to do something useful' script, from what I can tell. I would even go so far as to say that the entirety of the BBQ is just neat proof of concepts over creative ideas, and so essentially, dealing with all user cases stifles creativity in creation. Let the end user modify anything as THEY need to serve their purpose if they're inspired by a concept that is presented. They should learn to fish, rather than being handed a perfectly cooked fish (so to speak).
