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.

I interview developers and information security people all the time. I always ask lots of questions about Linux. As far as I'm concerned:
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 777everything all this time? WTF! Immediate red flag this guy cannot be trusted with anything.Can I ask if the reverse applies, eg is having no idea how to use non Unix like OSes (like Windows) any kind of red flag? Kinda been considering trying to go into a tech career so that I can have a 9-5 office job (I've until recently worked in what would be considered "blue collar" jobs, recently switched to an education job, would be nice to just sit down in an office and use computers for a living). I've used (GNU/)Linux from a very young age (parents had an Ubuntu laptop), as my primary OS/daily driver since I was 13, and exclusively (i.e. got rid of my Windows partition due to Windows enshittification) since I was idk maybe 16 ish? So I'm pretty comfortable doing things in Linux. But I have a reputation for being a tech person among my friends and they ask me to fix their stuff sometimes and whenever it's a Windows problem I literally have no idea how to use the OS lol. So are Windows skills and knowledge also expected for tech jobs or just Linux/Unix-like?
There's not much to learn in Windows land! Learn how to set file permissions, how the registry works (and some important settings that use it), and how Active Directory works (it's LDAP) and you'll be fine.
If you're used to using Linux nothing will frustrate you more than being forced to use a Windows desktop. The stuff you use every day just isn't there. You can add on lots of 3rd party tools to make it better but it'll never measure up.
When you have to go out on the Internet to download endless amounts of 3rd party tools the security alarms in your head might start going off. Windows users have just learned over time to ignore them 🤣
Absolutely. I tried using Windows for gaming some years back when Wine wasn't as good and it was such a struggle. I was used to thinking there's more software for Windows since it's more widely used, but I was shocked at both how much software I used was Linux (or POSIX-compliant) only, some of which had no Windows alternative. I remember struggling so much to just try and get some files off a LUKS-encrypted drive on Windows and was shocked that there was basically no option at the time. I also hate how Windows users just download random exes off the web for all their programs. I only ever used chocolatey to install anything for that brief Windows stint.
