[Linux] Change of authority, owner, owning group

Introduction

When I touched the Linux environment for the first time in a long time, I forgot the Linux command quite a bit, so make a note of it.

Change permissions

chmod [mode] [file name or directory name]

• Use the "-R" option to recursively change the directory.

• The following page was easy to understand for the mode explanation. https://qiita.com/shisama/items/5f4c4fa768642aad9e06

Owner change

chown [user name] [file name or directory name]

• Use the "-R" option to recursively change the directory.

Change ownership group

chgrp [group name] [file name or directory name]

• Use the "-R" option to recursively change the directory.
