newtask(1)                                                         User Commands                                                        newtask(1)

NAME
       newtask - create new task and optionally change project

SYNOPSIS
       newtask [-p project] [-v] [-c pid | [-Fl]  [command...]]

DESCRIPTION
       The newtask command executes the user's default shell or a specified command, placing the executed command in a new task owned by the spec-
       ified project. The user's default shell is the one specified in the passwd database, and is determined using getpwnam().

       Alternatively, newtask can be used to cause an already running process to enter a newly created task. A project for the new task  can  also
       be  specified in this form of the command. This might be desirable for processes that are mission critical and cannot be restarted in order
       to put them into a new project.

       In the case that extended accounting is active, the newtask command can additionally cause the creation of a task accounting record marking
       the completion of the preceding system task.

OPTIONS
       The following options are supported:

       -c pid   Cause  a  running process to enter a newly created task. A project for the new task can also be specified using the -p option. The
                invoking user must either own the process or have super-user privileges.

                If the project is being changed, the process owner must be a member of the specified project,  or  the  invoking  user  must  have
                super-user  privileges. When the project is changed for a running process, its pool binding as well as resource controls are modi-
                fied to match the configuration of the new project. Controls not explicitly specified in the project entry is preserved.

                This option is incompatible with the -F and -l options.

       -F       Creates a finalized task, within which further newtask or settaskid(2) invocations would fail. Finalized tasks can  be  useful  at
                some sites for simplifying the attribution of resource consumption.

       -l       Changes the environment to what would be expected if the user actually logged in again as a member of the new project.

       -p       Changes the project ID of the new task to that associated with the given project name. The invoking user must be a valid member of
                the requested project, or must have super-user privileges, for the command to succeed. If no project name is  specified,  the  new
                task is started in the invoking user's current project.

       -v       Verbose: displays the system task id as the new system task is begun.

OPERANDS
       The following operands are supported:

       project         The  project  to  which  resource usage by the created task should be charged. The requested project must be defined in the
                       project databases defined in nsswitch.conf(4).

       command         The command to be executed as the new task. If no command is given, the user's login shell is invoked. (If the login  shell
                       is not available, /bin/sh is invoked.)

EXAMPLES
       Example 1: Creating a New Shell

       The following example creates a new shell in the canada project, displaying the task id:

       example$ id -p
       uid=565(gh) gid=10(staff) projid=10(default)
       example$ newtask -v -p canada
       38
       example$ id -p
       uid=565(gh) gid=10(staff) projid=82(canada)

       Example 2: Running the date Command

       The following example runs the date command in the russia project:

       example$ newtask -p russia date
       Tue Aug 31 11:12:10 PDT 1999

       Example 3: Changing the Project of an Existing Process

       The following example changes the project of the existing process with a pid of 9999 to russia:

       example$ newtask -c 9999 -p russia

EXIT STATUS
       The following exit values are returned:

       0        Successful execution.

       1        A fatal error occurred during execution.

       2        Invalid command line options were specified.

FILES
       /etc/project    Local database containing valid project definitions for this machine.

       /proc/pid/*     Process information and control files.
