When typing:
mv /home/user/MyDocs/wepon /user/bin
mv /home/user/MyDocs/wepoff /user/bin

It says nothing, but that's ok, I guess?

Then I'll type:
chmod +x /user/bin/wepon
or
chmod +x /user/bin/wepoff

It says: chmod: /user/bin/wepoff: No such file or directory

How could this be ?

Step 3:
Download this package, extract it to MyDocs (main folder on your Nokia N900), and then insert this commands in a rooted X-Terminal window on your device:

# mv /home/user/MyDocs/wepon /usr/bin/
# mv /home/user/MyDocs/wepoff /usr/bin/
# chmod +x /usr/bin/wepon
# chmod +x /usr/bin/wepoff

try /usr/bin instead of /user/bin
you might need root privileges for the above to work

Thanks for replying, although I didn't noticed that it already was '/user/', so I changed into '/usr/', I feel stupid.

Anyway, thanks.
