This requires wvWare, which under Debian is in the wv package. Alternative converters can be used, e.g., jodconverter, which uses OO.O instead (no X server need be running.)

I submitted a command like this without $0 if $BASH_SOURCE is unset. Therefor, it did only work when using ./script, not using 'sh script'. This version handles both, and will set $mydir in a script to the current working directory. It also works on linux, osx and probably bsd.
0mydir=$(cd $(dirname ${BASH_SOURCE:-$0});pwd) -

It starts in the current working directory. It removes the empty directory and its ancestors (unless the ancestor contains other elements than the empty directory itself). It will print a failure message for every directory that isn't empty. This command handles correctly directory names containing single or double quotes, spaces or newlines. If you do not want only to remove all the ancestors, just use:
find . -empty -type d -print0 | xargs -0 rmdir0find . -empty -type d -print0 | xargs -0 rmdir -p -
These series of commands allows you all at once to make a backup of your current config, edit that config, then saves it as the running config and makes it persistent. I would advise knowing what your doing to the config before running this because if you mess up say the port 22 portion, you may get knocked off the system. ;) Don't say I didn't warn ya!

In My Case I Get Bash Full Suport Only Through ADB And Also A Decent Python Interpreter Using Python For Android.
