Here, we will explain about files </ b> and directories </ b>. Do you know the file? To put it very simply, an Excel file or a word file is a file.
Have you heard of the directory? If you're using a Mac, you may have heard of it. You don't hear about Windows. Think of a directory as a folder. A folder is a collection of multiple files and folders. Folder inside the folder ,,? It may be, but ... For example, if you want to divide the files for January and February in the 2020 folder, the January folder (the files for January are collected) and the February folder (2) in the 2020 folder. It will be easier to understand if you think that you are creating a file for the month).
Well, to the main subject Let's actually check the file on the terminal.
Before that, let's create a neko user using the useradd command. Let's also create a home directory with the -m (--create-home) option. (Simply think of your home directory as a private room where neko users can create files, because you can't create files in other directories without permissions)
［root@localhost ］# useradd -m neko
[neko@localhost ~]$ ls
tyu-ru.txt nabe.txt
In the above case, the files tyu-ru.txt and nabe.txt exist. Use the touch </ b> </ font> command to create a mike-neko file.
[neko@localhost ~]$ touch mike-neko.txt
Let's check the file again.
[neko@localhost ~]$ ls
tyu-ru.txt nabe.txt mike-neko.txt
It's completed. As an aside, ls stands for LiSt files. On Linux, commands with names that omit English are common. It is helpful to have this idea in mind as you learn commands.
Copy the created mike-neko file and create a kuro-neko file. Use the cp </ b> </ font> command.
[neko@localhost ~]$ cp mike-neko.txt kuro-neko.txt
Let's check if the file copy is done well with the ls command.
[neko@localhost ~]$ ls
tyu-ru.txt nabe.txt mike-neko.txt kuro-neko.txt
Did you do it well?
Let's rename the file. Use the mv </ b> </ font> command. mv </ b> </ font> is often used when moving files. Let's change the kuro-neko file to the siro-neko file.
[neko@localhost ~]$ mv kuro-neko.txt siro-neko.txt
Now let's check the changes.
[neko@localhost ~]$ ls
tyu-ru.txt nabe.txt mike-neko.txt siro-neko.txt
It has been changed.
Let's delete the file. Use the rm </ b> </ font> command. Delete the tyu-ru.txt file.
[neko@localhost ~]$ rm tyu-ru.txt
Now for confirmation.
[neko@localhost ~]$ ls
nabe.txt mike-neko.txt siro-neko.txt
How about that?
Let's leave it around here this time.
Let's remember the command.
