What is the command line for, how is it connected to the computer? What are batch files used for?

Question

Command line

Command line commands were passed at the university. Created files, copied, renamed, etc. But why did all this need to be done through the command line if it was much faster to do it manually?
In addition to this, batch files were created using simple examples. What are batch files for?

Answer 1

Firstly, not everything can be done through the GUI (that is, poking the mouse on the windows). Secondly, there may not be a gui at all (for example, a server) and there is simply nowhere to poke the mouse. Thirdly, about "faster" in gue, this is an extremely controversial issue. Faster only if you do not know and do not know how to use the command line. In the fourth, there are other OSes besides the windows, if you are not aware, and there, in these "other OSes" there is nothing to do at all without a command line, unless of course you use a computer not only to go to classmates and play tanks ...
Batch files this is generally a separate song, these are scripts for performing any tasks, and for example, bash is a fairly developed programming language. And they are used everywhere to automate many operations and processes.
