I'm trying to move my wsgi file to the /var/www/test directory to use Apache in Python.
While doing that, I found out that I could not copy the wsgi file to that directory or save the file there.
It said 'Permission Denied'.

I've researched various questions, but I couldn't solve the problem, so I'm posting this here.

Here's what I've done so far.

1. Changed .bash_profile file's path to like this.

PATH="$HOME/bin:/usr/local/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/bin:/bin"

reference: Addgroup: command not found

2. Confirmed that the PATH has "/usr/sbin"

~ $ echo $PATH

Output: /usr/local/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/bin:/bin

reference: https://superuser.com/questions/180898/groupadd-command-not-found

3. Logged in as root by 'sudo -i' and went to the /usr/sbin/ directory by cd command, but couldn't find the 'groupadd' directory.

Still, the groupadd command is not working.
The 'Command not found' message appears.

Some says it might be due to the lack of 'shadow-utils' package, but I'm not sure if it's okay to install that package for my problem.
That package seems to be related to CentOS, according to other people's reply on other questions..

However, I just don't know anything about Linux and which Linux I'm using by Mac Terminal...so I'm trying to figure it out.

One person say,

groupadd is part of the package "shadow".
Maybe that is not installed on OBS when it tries to install your
package? Try to Require it explicitely. In your case the correct thing
would be to add a line like this to your spec file

Requires(pre): /usr/sbin/groupadd

but, what does it mean by 'spec file'?

What I'm trying to do is,

sudo groupadd varwwwusers
sudo adduser www-data varwwwusers
sudo chgrp -R varwwwusers /var/www/
sudo chmod -R 760 /var/www/

What can I do more from where I am now?
I really need help.
