Free up Android internal storage

The internal storage on my Android phone was running out.  Un-installing apps and deleting files did not help; the space would just disappear again.

Found out that the route cause was the log files getting out of control.  Of my 2GB storage, about 1.7GB were taken up with logs.

Using the terminal emulator on the phone you can see the directory sizes:

    su
    cd /data
    du -Hd 1

and then delete the logs:

    rm -r log

And do the same for these logs:
/sdcard/logs
