How to Use prctl to Display, Replace, and Verify the Value of a Control on a Project

1. Become root or assume an equivalent role.
2. Display the value of project.cpu-shares in the project group.staff.

   # prctl -n project.cpu-shares -i project group.staff
   project: 2: group.staff
   NAME    PRIVILEGE       VALUE    FLAG   ACTION     RECIPIENT
   project.cpu-shares
           usage               1
           privileged          1       -   none               -
           system          65.5K     max   none 

3. Replace the current project.cpu-shares value 1 with the value 10.

   # prctl -n project.cpu-shares -v 10 -r -i project group.staff

4. Display the value of project.cpu-shares in the project group.staff.

   # prctl -n project.cpu-shares -i project group.staff
   project: 2: group.staff
   NAME    PRIVILEGE       VALUE    FLAG   ACTION     RECIPIENT
   project.cpu-shares
           usage               1    
           privileged          1       -   none                                 -
           system          65.5K     max   none
