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.

I have an interesting task in front of me. For reasons not important right now, I had to change the UID from a user from 105 to 700. Now, as expected all files and dirs are showing with 105. I need to replace all dirs/files with the new UID. How can I do that?
I tried using LS and FIND and grep the output file. The idea I had was to then use CHOWN but an easier way gotta be out there. There are thousands of files and dirs...
for file in $(find / -uid 105 -print 2>/dev/null)
echo chown 700 $file
Test with the echo cmd there, remove echo if you are happy. Needs to run as root.
This fails for paths with whitespace. It also enters places no one should go, like /proc (which will include processes owned by most users), and tries to chown things located there. Newbies need to be warned of the risks in basing a search at '/'.
