NAME

graphics − access graphical and numerical commands

SYNOPSIS

graphics [ −r ]

DESCRIPTION

Graphics appends the path name /usr/bin/graf to the current $PATH value, changes the primary shell prompt to ^, and executes a new shell.  The directory /usr/bin/graf contains all of the Graphics subsystem commands.  If the −r option is given, access to the graphical commands is created in a restricted environment; that is, $PATH is set to /:rbin:­/usr/rbin:­/bin:­/usr/bin:­/usr/bin/graf and the restricted shell, rsh(1), is invoked. To restore the environment that existed prior to issuing the graphics command, type EOT (control-d on most terminals).  To logoff from the graphics environment, type quit. 

The command line format for a command in graphics is command name followed by argument(s).  An argument may be a file name or an option string.  A file name is the name of any UNIX file except those beginning with −.  The file name − is the name for the standard input.  An option string consists of − followed by one or more option(s).  An option consists of a keyletter possibly followed by a value.  Options may be separated by commas. 

The graphical commands have been partitioned into four groups. 

Commands that manipulate and plot numerical data; see stat(1G).

Commands that generate tables of contents; see toc(1G).

Commands that interact with graphical devices; see gdev(1G) and ged(1G).

A collection of graphical utility commands; see gutil(1G).

A list of the graphics commands can be generated by typing whatis in the graphics environment.
