There should be a "Linux hotline" community where people can post whatever is stopping them from switching and get solutions
Elsewhere, Linux support areas seem more likely than not to have a large contingent of “WHY ARE YOU ASKING A DUMB QUESTION, you horror of a human being? Why didn’t you Search the site for words you don’t know using our broken search engine, instead of infecting us with your congenital idiocy?” folks.
I use Arch too!
exactly, I admit to sharing some of the "bro its so easy" attitude, but that should result in simple answers instead of berating, like a "no stupid questions" but for linux thing
A "no stupid questions" for Linux would be super helpful. A big one for me is shell commands. Like are shell commands different between distros, or do I have to install something to have certain commands? How do I even know what commands I do have?
Yes and no, kinda. So the most popular shell by far is Bash, which includes its own built in functions, and can also be extended with custom functions which certain distros may include in your bash config file by default. But generally, Bash and the GNU coreutils are standard, although some more "hip" distros will include other shell prompts such as zsh or fish by default, but even those tend to come with bash for script compatibility or easy switching for user preference. Some distros may include programs by default, but most of the time those are easily available in other distros through the package manager.
compgen -c(orcompgen -c | morefor a scrollable list (pressqto exit)) should do the trick, but that is a built-in bash command that may not be available on other shells, but generally you can find all the programs able to be called from shell inside the/bin
/sbin
/usr/bin
and
/usr/sbin
directories. All these directories are added to a variable called $PATH, and when you type a command into your shell, these are the places that get searched for a matching program to run. You can use
echo $PATHto see all the directories on your machine which are searched, or even add your own directory containing custom scripts or utilities so you can use them anywhere like an installed program.rtfm
