In the command mkdir -m 700 ~/project/digital_garden/private, the -m 700 part is used to set specific permissions for the new directory right when it's created.
Let's break down 700:
- The number
7refers to the permissions for the owner of the directory. - The first
0refers to the permissions for the group that owns the directory. - The second
0refers to the permissions for others (anyone else).
Each digit is a sum of these values:
4for read permission (r)2for write permission (w)1for execute permission (x)
So, 700 means:
- Owner (7):
4(read) +2(write) +1(execute) =rwx(read, write, and execute permissions) - Group (0): No permissions (
---) - Others (0): No permissions (
---)
This configuration ensures that only you (the owner) can read, write, or execute anything within the private directory, making it very secure.
