This section provides examples of commands and options used with projects and tasks.
Use the ps command with the –o option to display task and project IDs. For example, to view the project ID, type the following:
# ps -o user,pid,uid,projid USER PID UID PROJID jtd 89430 124 4113
Use the id command with the –p option to print the current project ID in addition to the user and group IDs. If the user operand is provided, the project associated with that user's normal login is printed:
# id -p uid=124(jtd) gid=10(staff) projid=4113(booksite)
To match only processes with a project ID in a specific list, use the pgrep and pkill commands with the –J option:
# pgrep -J projid-list # pkill -J projid-list
To match only processes with a task ID in a specific list, use the pgrep and pkill commands with the –T option:
# pgrep -T taskid-list # pkill -T taskid-list
To display various statistics for processes and projects that are currently running on your system, use the prstat command with the –J option:
$ prstat -J

The cron command issues a settaskid to ensure that each cron, at, and batch job executes in a separate task, with the appropriate default project for the submitting user. The at and batch commands also capture the current project ID, which ensures that the project ID is restored when running an at job.
The su command joins the target user's default project by creating a new task, as part of simulating a login.
To switch the user's default project by using the su command, type the following:
# su - user
