From time to time I need to find or track files in folder and sub-folders changed in a last few days, and command bellow do job easy and fast.

    find . -type f -exec stat -c "%y %n" {} + | sort -r | head -15

Also I have it inside .bash_aliases :

    alias findrecent='find . -type f -exec stat -c "%y %n" {} + | sort -r | head -15'
Above command will search current and all sub-folders for all files, sort them and show only last 15 files (based on change date/time attribute).

Very handy little command.

For some projects I needed to run startup scripts everytime when I start my ubuntu server. Here is little how-to with addition how to run some processes using non-sudo username (normal user account).

After some searching I found out that there is a small command that allows the root to run a process as a different user.
So when I had put “sudo -u burgerboydaddy” in front of my command it worked flawlessly.
