From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Would being a Linux "power user" increase my chances of getting a job in IT/tech? (lemmy.world)

I'm trying to get a job in IT that will (hopefully) pay more than a usual 9 to 5. I'm been daily driving Linux exclusively for about 2 1/2 years now and I'm trying to improve my skills to the point that I could be considered a so-called "power user." My question is this: will this increase my hiring chances significantly or marginally?

I interview developers and information security people all the time. I always ask lots of questions about Linux. As far as I'm concerned:

If you're claiming to be an infosec professional and don't know Linux you're a fraud.
If you're a developer and you don't know how to deploy to Linux servers you're useless.

So yeah: Get good with Linux. Especially permissions! Holy shit the amount of people I interview that don't know basic Linux permissions (or even about file permissions in general) is unreal.

Like, dude: Have you just been chmod 777 everything all this time? WTF! Immediate red flag this guy cannot be trusted with anything.

Sorry for your loss. I hit myself with the ‘rm -rf /*‘ several years back when I was actually trying to do ‘rm -rf ./*‘.

Now I do ‘ls’ instead of ‘rm’ just to make sure that what I’m deleting is what I’m intending to.

Figured I was very lucky that it was just on my own workstation and not on any of the servers I was tasked with maintaining. I lost a day or so of work. Had it been our dev server? Would’ve destroyed my team for a while.
