How can I list all users and groups and change their permissions?

I try to update Wordpress but my FTP user intranet_admin has not enough permissions and is unable to create a directory.

Update WordPress

Download the update from https://downloads.wordpress.org/release/en_US/wordpress-4.9.7.zip ...

Unzip the updated version ...

Directory could not be created.

The installation was not successfull

Edit: I found out that I can list all users with "cat /etc/passwd". I found this entry:


What do I have to change so that the user will have enough permissions for updating wordpress?

OT: Wordpress Problem solved!

I executed from within the Wordpress root directory:

find -type d -exec chmod 755 {} \;
find -type f -exec chmod 644 {} \;

and then:

chown -R wwwrun:ftp-users /path/to/my/wp-directory

This solved the problem and I was able to upgrade!

The permission to create a particular directory is not tied to the user account as tightly as you seem to think it is. That is, it's not part of the account's entry in /etc/passwd.

A user can create (or delete) a directory in another directory if that other directory is writable by the user or by a group that the user belongs to. This would also permit the user to create/delete files in that directory.


$ ls -ld .
drwxr-xr-x  2 myself  staff  512 May  4 16:29 .

Here, only the user myself can create and delete files and directories while everyone is able to access the directory and list the directory content (the x and r permissions).

$ ls -ld .
drwxrwxr-x  2 myself  staff  512 May  4 16:29 .

In this case, the myself user as well as all users in the group staff can create and delete files and directories in the current directory.
