What does the a+rw part does? I guess the r is for recursively changing the permissions.

[–] [email protected] 3 points 11 months ago* (last edited 11 months ago)

Here is the breakdown:

chmod is the command to change the mode of the files (-rwxrwxrwx)
-R is the recurse flag,
a means "all", you can also have u, g or o (respectively user, group and others) instead.
+ is add (you can remove with -),
rw is the permissions (rw of rwx)

I prefer changing permissions this way instead of using absolute values (0777 for instance) as it's easier to reverse if you made a mistake.

Add read/write permissions to all. -R is the recursive part.
