Omit the space and use quotes (optional):

files="./home/files"

Please keep in mind that the path "./home/files" is relative to the current working directory!

"break" and ";;" are in the wrong places, or did you post just a part of the script?

"no is not work" is a rude and discorteous but not a sufficient reaction to my suggestions.

It's not your English.  Just "it did not work" without any further explanation is not a bit better than your previous answer.

ah ok :)

i test your suggestions
my complete bash script
http://pastebin.com/w53cfdHF


files = "./files"

Open in new window


and i have a error

adnvideo.txt: No such file or directory

Open in new window


If the text is taken into the script it gives
python: can't open file 'adnplay.py': [Errno 2] No such file or directory
python: can't open file 'adnplay.py': [Errno 2] No such file or directory
python: can't open file 'adnplay.py': [Errno 2] No such file or directory
python: can't open file 'adnplay.py': [Errno 2] No such file or directory

I said "Omit the space", Why did you add spaces around the = sign" instead?

files="./files"

You're still aware that "." means "current directory", so that the path "./files" is relative to whatever directory you're in?

Add the following code just before your while loop:

if [ ! -f $files/adnplay.py ]
then
     echo "$files/adnplay.py does not exist or is not readable"
    exit 1
fi

gaaara had their problem solved with our help.   I suspect the language issue might be the reason they requested a delete.
