forgive me i'm not familiar with the syntax and shit for shellscript, but couldn't you just do something like count the files in your folder and if it is == 0 do something
check out http://stackoverflow.com/questions/13727069/count-files-and-directories-using-shell-script

>>51665834

for $f in "path/to/files/*" do
# bla bla
done

Or something like this. Use google m8.

>>51665834
Check for the size of the folder and under a certain threshold quite the loop?

Why this doesn't work?

 #!/bin/sh

echo "Starting to play music"
cd ./playlist
pwd
LIST=$(ls | wc -l)

while ($LIST > 0)
do

SONG=$(ls -r | tail -n 1)
echo $SONG
echo $LIST
sleep 3s


mplayer -volume 2 /var/www/html/vault/drive1/audio/playlist/$SONG

echo "Moving" $SONG
mv $SONG /var/www/html/vault/drive1/audio/played/

$LIST --1
echo "----Next----"

done

echo "Finished, out of fresh music."
 

>>51666352
Because $List isn't updated?

Why not just do something like

for $f in "files/*" do
play $f
done

mv "files/*" "some/other/place"

Isn't it paramount that you move each file individually after you've played it?

>>51666391
Disregard my first comment. I was to stupid to read what you wrote.

Can you clarify what you mean by "not working" is it looping forever, is it crashing?

>>51666413

 Starting to play music
/var/www/html/vault/drive1/audio/playlist
./play.sh: 8: ./play.sh: 2: not found
Finished, out of fresh music. 

This is the output and then it creates file called "0" in the /playlist directory.

>>51666352
>

$LIST --1

That's not a thing in sh

>>51666523
Neither is

while ($LIST > 0)

>>51666452
Which lines is 2 and 8?

You could do this:

for f in *;
do
    #play $f
    #move $f
done

Tested it and it works afaik.

>>51666555
>Which lines is 2 and 8?
That's not what it's saying.

>>51666452
I can't figure why its making a file yet but

>/var/www/html/vault/drive1/audio/playlist

if empty it should skip the while but isn't, no? something broke. maybe check if empty of a filetype not just empty.

>>51666584
>I can't figure why its making a file yet

$LIST > 0

writes the contents of $LIST to the file "0"

Seriously OP learn shell scripting before you try this shit. Half the stuff you're trying to do isn't even valid and you're just incorrectly guessing at syntax

>>51666576
What does it mean then?

It has nothing to do with what
>>51666523
and
>>51666544

pointed out then?

>>51666523
How do I make it to be 1 less after every loop?
>>51666544
Okay, I'm stupid.

>>51666555
I don't know how I should sort that out?

>>51666584
When /playlist is empty it just loops the echos and says that it can't play anything.

/sp/ get

#!/bin/bash
PLAYLIST=/path/to/playlist
PLAYED=/path/to/played

printf "Starting to play music. \n"
for i in "$PLAYLIST" ; do 
 printf "\n Now playing "$i" \n".
 mplayer -volume 2 $i
 printf "\n Moving "$i" to the played directory \n"
 mv $i "$PLAYED"
 sleep 3s
done

printf "Done."

Why not like this?

>>51666636
>What does it mean then?

LIST=$(ls | wc -l)

is resulting in "8"

while ($LIST > 0)

is trying to execute "8" and write its output to the file "0"
"8" is not a command, so you get a not found error.

Basically this entire script is retarded

>>51666669
Yeah, I'll try this.
Thanks for writing it down so I can actually think how it works. <3

>>51666669
Just looking over this, I imagine it might fail when file names have spaces in them.

>>51666724
Enclose the variable in quotes

echo "$var"

>>51666709
For loops are really easy and useful, it's essentially saying "For every file in this directory, run these commands on it one after the other."

>>51666724
It shouldn't, all the variables should be encased in quotation marks. I understand where you're coming from though, I had problems with my ffmpeg batch converter until I quotation marked the fuck out of it.

>>51666669
>>51666724
I realized I missed some quotation marks, mplayer -volume 2 $i will probably need to be mplayer -volume 2 "$i"

>>51666775
>It shouldn't, all the variables should be encased in quotation marks
$i isn't

>>51666828
Yeah, I'm just now noticing the ones I missed. Sorry about that.

>>51666669
>>51666809
Uhm, almost...

Or use bash parameter expansion: ${var}

This should be done out of habit

>>51666901
>Cannot open file '/root/.mplayer/input.conf'
Are you running Mplayer as root?

>>51666901
>lel

Do you have any idea what you're doing, or just hoping to accidentally get something right?

>>51666969
Yes but that should still work.
>>51666971
I do have some sort of idea.

>>51666936
That doesn't fix the problem

AYY, I modified my original script and now it just werks.

 
#!/bin/bash

echo "Starting to play music"
cd ./playlist
pwd
LIST=$(ls | wc -l)

for ((i = 0; i <= $LIST; i++));
do

SONG=$(ls -r | tail -n 1)
echo $SONG
echo $LIST
sleep 3s


mplayer -volume 2 /var/www/html/vault/drive1/audio/playlist/$SONG

echo "Moving" $SONG
mv $SONG /var/www/html/vault/drive1/audio/played/


echo "----Next----"

done

echo "Finished, out of fresh music."
