Android Terminal Commands

chmod    - give/take rights away from files.The numbers you see in the how-to's is a little
                complicated.It has to do with the rights you are assigning the file or folder.

cat         -  look at,modify or combine a file.You can also copy files with this command by
                "reading" it to another file insted of to the screen.

cd          -  change from one directory to another

cp          -  Copy a file from one location to another

dd         -  copies exact locations to other locations.Can be an entire drive,a folder, etc,
                dd if= of=,uses an input file and an output file.

df          -  how much free disk space.In Linux you can add a switch "df -h" but the "-h"
                does nothing for me on Android.

du         - show disk usage of files.Add "-h" to get human readable.Especially useful when
               you add "-d1" to limit the directory depth to 1.If you run "du -h -d1".it will tell
               you how much space each directory occupies,including their contents summed.

exit       -  exits the shell you are in.When you type su you start up a shell.

grep     -  search within a file for a text string.Also useful for parsing command output.
              'ls | grep something' is a quick way to list files that contain the string "something"

            to ensure we've got all data written.
