Hello, I was wondering if it is possible to create a user on linux and leave it in a folder, and can not go back to a level above can only access the subfolders inside that folder.
/folder/user/Luiz < folder in which the person must log in
/folder/user < it cannot come to previous folder
/folder/user/Luiz/documents < it can access subfolders
-1
To change the folder where it will log in, you must edit within the file /etc/passwd the following information:
marcosrai:x:1000:1000:Marcos Rai Alves da Cunha,,,:/home/marcosrai:/bin/zsh
Where it is in bold you should put the folder wherever the user is when logging in.
To prevent it from going to the previous directories you should leave the previous folders with user permission at 770 or 700. In 770, only the owner of the directory and the group to which the directory belongs will have access to it, Already in 700 only the owner of the can access it.
How can you do this? By giving an ls -l, you will see the following result:
