.TH VIEW-OS 1 "August 8, 2009" "VIEW-OS: a process with a view"
.SH NAME
viewsudo \- execute a command as another (virtual) user
.SH "SYNOPSIS"
.HP \w'\fBsu\fR\ 'u
\fBviewsudo\fR [\fB-g \fIgroupname\fR|\fI#gid\fR] [\fB-u \fIusername\fR|\fI#uid\fR] \fIcommand\fR
.SH "DESCRIPTION"
.PP
\fBviewsudo\fR
allows a user to execute a command as the superuser or
another user in View-OS.
.SH OPTIONS
.PP
\fBviewsudo\fR accepts the following command line options:
.PP
\fB\-g\fR \fIgroup\fR
.RS 4
Normally, \fBviewsudo\fR sets the primary group to root.
The \fB\-g\fR option causes
sudo to run the specified command with the primary group
set to \fIgroup\fR. To specify a gid instead of a \fIgroup name\fR,
use \fI#gid\fR. When running commands as a gid, many shells
require that the ’#’ be escaped with a backslash (’\’). If
no \fB-u\fR option is specified, the command will be run as the
invoking user (not root). In either case, the primary
group will be set to \fIgroup\fR.
.RE
.PP
\fB\-u\fR \fIuser\fR
.RS 4
The \fB-u\fR option causes \fBviewsudo\fR to run the specified
command as a user other than \fRroot\fR. To specify a \fIuid\fR
instead of a \fIuser name\fR, use \fI#uid\fR. When running commands as
a uid, many shells require that the ’#’ be escaped with a
backslash (’\’).
.SH RETURN VALUES
Upon successful execution of a program, the exit status from \fBviewsudo\fR will
simply be the exit status of the program that was executed.
