I followed this steps

1) root
2) apt-get install wget #if you don't have it installed.

3) wget http://mohammadag.xceleo.org/public/...mediaplayer.sh

4) chmod +x install_mediaplayer.sh
5) ./install_mediaplayer.sh

(without number))

shows...

chmod: /usr/local/bin/mediaplayer: No such file or directory
-sh: exec: line 1: /usr/local/bin/mediaplayer: not found

what i did wrong?
