NAME

gutil − graphical utilities

SYNOPSIS

command-name [options] [files]

DESCRIPTION

Below is a list of miscellaneous device independent utility commands found in /usr/bin/graf.  If no files are given, input is from the standard input.  All output is to the standard output.  Graphical data is stored in GPS format; see gps(5).

bel
 − send bel character to terminal

cvrtopt [= sstring fstring istring tstring ]  [ args ]
 − options converter
Cvrtopt reformats args (usually the command line arguments of a calling shell procedure) to facilitate processing by shell procedures.  An arg is either a file name (a string not beginning with a −, or a − by itself) or an option string (a string of options beginning with a −).  Output is of the form:
−option −option . . . file name(s)
All options appear singularly and preceding any file names. Options that take values (e.g., −r1.1) or are two letters long must be described through options to cvrtopt.  Cvrtopt is usually used with set in the following manner as the first line of a shell procedure:
set − `cvrtopt =[options] $@`
Options to cvrtopt are:

sstring String accepts string values. 

fstring String accepts floating point numbers as values. 

istring String accepts integers as values. 

tstring String is a two letter option name that takes no value. 

String is a one or two letter option name. 

gd [GPS files ]
 − GPS dump
Gd prints a human readable listing of GPS. 

gtop [− rnu ]  [GPS files ]
 − GPS to plot(5) filter
Gtop transforms a GPS into plot(5) commands displayable by plot(1G) filters.  GPS objects are translated if they fall within the window that circumscribes the first file unless an option is given. 
Options:

rn translate objects in GPS region n. 

u translate all objects in the GPS universe. 

pd [ plot (5) files ]
 − plot(5) dump
Pd prints a human readable listing of plot(5) format graphical commands.

ptog [ plot (5) files ]
 − plot(5) to GPS filter
Ptog transforms plot(5) commands into a GPS. 

quit
 − terminate session

remcom [ files ]
 − remove comments
Remcom copies its input to its output with comments removed.  Comments are as defined in C (i.e., /∗ comment ∗/). 

whatis [− o ]  [ names ]
 − brief online documentation
Whatis prints a brief description of each name given.  If no name is given, then the current list of description names is printed.  whatis \∗ prints out every description. 
Option:

o just print command options

yoo file
 − pipe fitting
Yoo is a piping primitive that deposits the output of a pipeline into a file used in the pipeline.  Note that, without yoo, this is not usually successful as it causes a read and write on the same file simultaneously.
