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.

Yes, I use shellcheck in the editor. Its pretty useful. But running (a little bit more complex commands) in the terminal directly won't help with shellcheck. That's why I also have a functionality to directly load and edit the current command in the terminal in (Neo)vim and edit and when closing Vim the command gets executed. The benefit doing this is getting checked by shellcheck in the editor and also it makes it easier to one-off complex commands.
Thanks to shellcheck I got in the habbit to always enclose variables in
${var}. And recently learned from a community member that using[[ expr ]]style has basically no downsides against using[ expr ]directly.
