The deployment is complete for the time being. If you write a readme, arrange the submissions, and deal with errors, I wonder if the appearance as a spectacle will be completed. A tweet from an omnivorous person said that portfolios can be evaluated not only for server-side ability, but also for content ability and appearance (I broke it down). I haven't got the server-side description and ability yet, but I can do it well if I don't cut corners, so I'm going to make a work that does my best now.
Know the number following chmod.
It's the type of permissions on the file
chmod is an abbreviation of "change mode", and edit authority is set by the combination of the number of digits and numbers. This will help prevent unauthorized access from third parties.
|Number of digits||meaning|
|1st digit (hundreds digit)||Scope of access rights of the owner|
|2nd digit (tens digit)||Scope of access rights for the group|
|3rd digit (1st place)||Scope of access rights for other users|
Authority will increase by adding numbers. For example, for all privileges 4 + 2 + 1 + 0 to 7 If you only read and write, 4 + 2 will be 6. You can set the users who can edit in this way.
There are a lot of other Linux commands, so think of them as part of them.
