http://wiki.openstreetmap.org/wiki/Osmosis/Installation

LANG=en_US.UTF-8  wget http://bretth.dev.openstreetmap.org/osmosis-build/osmosis-latest.tgz

linux-wyee:/home/martin # cd osmosis-0.39
bash: cd: osmosis-0.39: Datei oder Verzeichnis nicht gefunden
linux-wyee:/home/martin # chmod a+x bin/osmosis
chmod: Zugriff auf „bin/osmosis“ nicht möglich: Datei oder Verzeichnis nicht gefunden
linux-wyee:/home/martin # bin/osmosis
bash: bin/osmosis: Datei oder Verzeichnis nicht gefunden

the last lines mean;

bash: cd: osmosis-0.39: Datei oder Verzeichnis nicht gefunden

So we have some intersting lines at the end:

bash: cd: osmosis-0.39: file or directory was not found 
chmod: no access on „bin/osmosis“ it is not possible to access "bin/osmosis": file or direcory werent found 
linux-wyee:/home/martin # bin/osmosis
bash: bin/osmosis: directory or file werent found

so what!? what goes wrong here. What can we do here to install osmosis in a correct way!? thx for any and all help...
