wallpaper manager

So, I have been looking for a wallpaper manager with some features like:

1. automatically change wallpaper from my directory list

2. Get wallpapers from internet

Possibly display time and a quote.

Variety does all of that. From variety website :

Variety is a wallpaper manager for Linux systems. It supports numerous desktops and wallpaper sources, including local files and online services: Flickr, Wallhaven, Unsplash, and more.

Where supported, Variety sits as a tray icon to allow easy pausing and resuming. Otherwise, its desktop entry menu provides a similar set of options.

Directories with maximum number of files

Lot of times, I want to find the directories with maximum number of files and so I wrote this quick function to do exactly the same

function count_lines ()
{
    oldIFS=$IFS
    count=0
    IFS=$'\n'
    dir=${1:-.}
    cd $dir
    find . -type d |while read line
    do
        echo -n "$(find $line -type f |wc -l) $line"
        echo 
        printf "Directories :: %8d\r" $count >&2
        ((count++))
    done|sort -n
    IFS=$oldIFS
}   # ----------  end of function count_lines  ----------

xev -event keyboard

Pretty neat 🙂

rats – source code analysis

I stublemed across this recently so thought of sharing this for you 🙂

sudo yum install rats

And some details about rats

RATS(Rough Auditing Tool for Security) scans through code, finding potentially

dangerous function calls. The goal of this tool is not to definitively find bugs (yet). The current goal is to provide a reasonable starting point for performing manual security audits. The initial vulnerability database is taken directly from things that could be easily found when starting with the forthcoming book, “Building Secure Software” by Viega and McGraw.
