generating permissions/htaccess

[voessli]

Hallo!
i am quite new to server administration. I have Plesk 7.5 and want to create many permissions for folders, but it takes almost half an hour to make 50 entries for the same user
The same thing when i have to remove the user again..
Is there a way to accelerate this procedure?

I am managing just a VServer via browser access from a PC (Windows). I was advised to use the command line, unfortunately i cant find it.

Thanks!
