Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Audacity's noise removal filter did a good job but left me with some ugly artifacts that did not suit my needs.
You can set the creation date of a picture or video as its access and modification time: If the creation date was saved in the exif data of some media, you can extract it with "exiftool -ee -CreateDate" and then "touch" the file with that time.
To do this automatically save the following script e.g. as /usr/local/bin/exiftool_set_create_date
# exiftool_set_create_date: set the file date from exif "Creation Date".
echo -n "$@:
I couldn't find one to suit anywhere so wrote this.
It is not really needed during shutdown because all it does is send SIGTERM to all the rsync server processes and the Linux shutdown process does that anyway. rsync server processes are well behaved and do terminate quickly in response to SIGTERM so there's no need to check that the processes have terminated and escalate to SIGKILL (which the Linux shutdown process does anyway).
