.TH GRAPHICS 1G
.SH NAME
graphics \- access graphical and numerical commands
.SH SYNOPSIS
.B graphics
[ \fB\-r\fP ]
.SH DESCRIPTION
.I Graphics\^
appends the path name
.B /usr/bin/graf
to the current
.B $\s-1PATH\s+1
value,
changes the primary shell prompt to \fB^\fR,
and executes a new shell.
The directory
.B /usr/bin/graf
contains all of the Graphics subsystem commands.
If the \fB\-r\fR option is given,
access to the graphical commands is created
in a restricted environment;
that is,
.B $\s-1PATH\s+1
is set to
\fB/:rbin:\%/usr/rbin:\%/bin:\%/usr/bin:\%/usr/bin/graf\fR
and the restricted shell,
.IR rsh (1),
is invoked.
To restore the environment that existed prior to
issuing the
.I graphics\^
command, type
.B \s-1EOT\s+1
(control-d on most terminals).
To logoff from the graphics environment,
type
.BR quit .
.PP
The command line format for a command in
.I graphics\^
is \fIcommand name\fR followed by \fIargument\fR(s).
An \fIargument\fR may be a \fIfile name\fR or an \fIoption string\fR.
A \fIfile name\fR is the name of any \s-1UNIX\s+1 file except those
beginning with \fB\-\fR.
The \fIfile name\fR \fB\-\fR is the name for the standard input.
An \fIoption string\fR consists of \fB\-\fR followed by one or more \fIoption\fR(s).
An \fIoption\fR consists of a keyletter possibly followed by a value.
\fIOptions\fR may be separated by commas.
.PP
The graphical commands have been partitioned into four groups.
