i want to create unix user account (usera) for outsider so that they can run program that exist in /application/xxx/.
The account have their own home directory (/home/usera).
But on the same time the user cannot run any application/command either than in /application/xxx/.
User can only browse their own home directory and avoid from accessing others.
