The full path is repeating the path to the file after calling “adb command”
so in my case I am on a mac snow leopard 10.6.3 using terminal. When ever I open terminal
my USER folder is the default path it opens to. My androidsdk folder is located in my USER folder,
so every time I refer to the file in that folder I use the full path androidsdk/adb command.
so instead of simple writing adb push try3
I would write
my-macbook:~ USER$ androidsdk/tools/adb push androidsdk/tools/try3 /data/local

If you don’t want you type the full path to your tools directory every time. You will need to edit your .bash_profile.
To do that open up terminal if you are on a mac and type ” nano ~/.bash_profile ”
then type export PATH=${PATH}:/tools. In my case it was “export PATH=${PATH}:androidsdk/tools”
then hit “control O” to write out which saves it.
Type in a name to save it as. confirm
Then hit “control X” to exit. Once back in terminal you can issue commands to the “adb” tool without having to navigate to the
“tools”directory.
