"Spend enough time on the command line and you'll eventually want to do many tasks…that take some intricate commands…repeatedly. A good example of this, is making thumbnails of photos. Basically, our workhorse of this script is not ImageMagick (which provides convert, identify and mogrify), but the for loop in bash itself. Ready? Grab your pen-knife and let's whittle out a script:"

"8.2. Managing System Services Note To expand your expertise, you might also be interested in the Red Hat System Administration II (RH134) training course. Previous versions of Red Hat Enterprise Linux, which were distributed with SysV init or Upstart, used init scripts located in the /etc/rc.d/init.d/ directory. These init scripts were typically written in Bash, and allowed the system administrator to control the state of services and daemons in their system. In Red Hat Enterprise Linux 7, these init scripts have been replaced with service units. "

" Few days ago, I came across a Centos 7 32-bit distro and I felt the desire to test it on an old 32-bit machine. After booting I realized that it had a bug and it was loosing the network connection, which I had to turn it "up" manually every time after boot. So, the question was how could I set a script doing this job, running every time I boot my machine?"

"January 07, 2016 The first WordPress update of 2016 is out and like many other incremental updates, it is being triggered by a security vulnerability. The single security issue being patched in WordPress 4.4.1 is a cross site scripting vulnerability that could have potentially enabled a site compromised."

"Once you get over systemd's rude departure from the plain-text, script-laden System V of yore, it turns out to be quite nifty and comes with an equally nifty toolbox. In this article, we'll be looking at four of those tools, plus one you're probably already familiar with but haven't used in the way you will see here."

" 80 down vote favorite 43 To work around bug #1005495 (changing LCD brightness via hotkeys impossible), I'd like to have one command line query for increasing and one for reducing the brightness of my LCD. I could then map a hotkey to each one of this queries. The problem is: I don't know how to increase and reduce the LCD brightness on the command line. Do you?"

[Rules to live by It's not just knowing how to set up and maintain your servers and understanding how system commands work that makes you a good system administrator -- or even knowing how to fix things when something breaks down, how to monitor performance, how to manage backups, or how to craft superbly clever scripts.

"I recently stumbled upon an interesting tiny old script which can translate any text you select. After highlighting the text, be it in a web browser, Libreoffice or PDF document and so on, upon using a keyboard shortcut, its translation is displayed in a desktop notification."

"For years, I've wanted to learn Vim, now my preferred Linux text editor and a favorite open source tool among developers and system administrators. And when I say learn, I mean really learn. Master is probably too strong a word, but I'd settle for advanced proficiency. For most of my years using Linux, my skillset included the ability to open a file, use the arrow keys to navigate up and down, switch into insert mode, change some text, save, and exit."

"While I was putting together slides for my lightning talk at Great Wide Open (happening March 16-17), Not that Weird: Open Source Tools for Creatives, I remembered that in the last half of 2015 we had a bit of a loss from our open source creative toolbox. I think I was little"
