4.3. Checking Permissions from Scripts

The pkcheck utility, which checks whether a process is authorized for action, now supports a new format for parameters specified by the --process option. This makes running pkcheck safer by avoiding a race condition. The new format looks as follows:
$ pkcheck --process pid,start-time,uid 


Do not use the bare pid or pid,start-time formats for the --process option. All scripts that invoke pkcheck need to use the new format pid,start-time,uid to avoid a race condition.
For more information, see the pkcheck(1) man page.
