A good Bash course?

Question

I searched Google for a bash course, but there are so many... Which one do you think to be good?

Answer 1

It is useless to learn the whole bash, you should learn commands that you will use only. Look for basic commands first, then read advanced ones depending on your needs

Answer 2

Thanks for answering, but learning Bash syntax allows you to write scripts, or more complex commands... Don't you agree?

Answer 3

Yes, I just started learning C (a few days ago), but I didn't mean *build* commands, but using several together (such as:
me@mycpu:~$ ps -e | grep someprocess
- the only I know... - )

Answer 4

You don't need to learn bash in order to write commands, you can write commands with almost any programming language

Answer 5

By the way, bash commands are actually just 'commands' that run scripts, and most of those scripts are in C, so if you really wanna make you own commands try learning C and it's libraties, it will be way more powerful (althought C language isn't as powerful as it was)

Answer 6

I see, well here are the commands I use the most:
ls, grep, pwd, chmod, cd, rm, cp, mv, ln, mkdir, man, cat, head, vim, ps, kill (All I can remember right now)
Most of them are basic, which is why I said it is useless to learn all of them cause there are way too many. (You can dm me for more help if you want)
EDIT:
Sorry I answered too long, I don't have any links, I learned commands by searching them one by one when I use them, and then I get get used to them after 2 or 3 times of looking online)
