.TH NEWTASK 1 "Nov 17, 2004"
.SH NAME
newtask \- create new task and optionally change project
.SH SYNOPSIS
.LP
.nf
\fBnewtask\fR [\fB-p\fR \fIproject\fR] [\fB-v\fR] [\fB-c\fR \fIpid\fR | [\fB-Fl\fR] [\fIcommand...\fR]]
.fi

.SH DESCRIPTION
.sp
.LP
The \fBnewtask\fR command executes the user's default shell or a specified
command, placing the executed command in a new task owned by the specified
project. The user's default shell is the one specified in the \fBpasswd\fR
database, and is determined using \fBgetpwnam()\fR.
.sp
.LP
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.
.sp
.LP
In the case that extended accounting is active, the \fBnewtask\fR command can
additionally cause the creation of a task accounting record marking the
completion of the preceding system task.
.SH OPTIONS
.sp
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB-c\fR \fIpid\fR\fR
.ad
.RS 10n
Cause a running process to enter a newly created task. A project for the new
task can also be specified using the \fB-p\fR option. The invoking user must
either own the process or have super-user privileges.
.sp
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 modified to match the configuration of the new project.
Controls not explicitly specified in the project entry is preserved.
.sp
This option is incompatible with the \fB-F\fR and \fB-l\fR options.
.RE

.sp
.ne 2
.na
\fB\fB-F\fR\fR
.ad
.RS 10n
Creates a finalized task, within which further \fBnewtask\fR or
\fBsettaskid\fR(2) invocations would fail. Finalized tasks can be useful at
some sites for simplifying the attribution of resource consumption.
.RE

.sp
.ne 2
.na
\fB\fB-l\fR\fR
.ad
.RS 10n
Changes the environment to what would be expected if the user actually logged
in again as a member of the new project.
.RE

.sp
.ne 2
.na
\fB\fB-p\fR\fR
.ad
.RS 10n
Changes the project \fBID\fR 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.
.RE

.sp
.ne 2
.na
\fB\fB-v\fR\fR
.ad
.RS 10n
Verbose: displays the system task id as the new system task is begun.
.RE

.SH OPERANDS
.sp
.LP
The following operands are supported:
.sp
.ne 2
.na
\fB\fIproject\fR\fR
.ad
.RS 11n
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
\fBnsswitch.conf\fR(5).
.RE

.sp
.ne 2
.na
\fB\fIcommand\fR\fR
.ad
.RS 11n
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, \fB/bin/sh\fR is
invoked.)
.RE

.SH EXAMPLES
.LP
\fBExample 1 \fRCreating a New Shell
.sp
.LP
The following example creates a new shell in the \fBcanada\fR project,
displaying the task id:

.sp
.in +2
.nf
example$ \fBid -p\fR
uid=565(gh) gid=10(staff) projid=10(default)
example$ \fBnewtask -v -p canada\fR
38
example$ \fBid -p\fR
uid=565(gh) gid=10(staff) projid=82(canada)
.fi
.in -2
.sp

.LP
\fBExample 2 \fRRunning the \fBdate\fR Command
.sp
.LP
The following example runs the date command in the \fBrussia\fR project:

.sp
.in +2
.nf
example$ \fBnewtask -p russia date\fR
Tue Aug 31 11:12:10 PDT 1999
.fi
.in -2
.sp

.LP
\fBExample 3 \fRChanging the Project of an Existing Process
.sp
.LP
The following example changes the project of the existing process with a pid of
\fB9999\fR to \fBrussia\fR:

.sp
.in +2
.nf
example$ \fBnewtask -c 9999 -p russia\fR
.fi
.in -2
