A.1. - Installing the software
The C-PLOT distribution is generally supplied
on magnetic media in
tar
format.
The amount of disk space required
for installation varies from computer to computer, but is usually
1.5 to 2.5 megabytes.
The directory hierarchy on the tar media has
the same structure as the final installation, so you need only choose
the place in your file system hierarchy to locate the C-PLOT
files.
C-PLOT expects to find its auxiliary
files either in the directory
/usr/cplot
or in the directory
/usr/local/cplot.
You can locate the C-PLOT
files somewhere else, however, and make
/usr/cplot
(or
/usr/local/cplot)
a symbolic link to that location
(if symbolic links are available with your version of UNIX)
or have each user set the environment variable
CPLOTHOME to
that location.
Once you have decided where to put C-PLOT, make
that directory, change to it if necessary and then extract the contents
of the tar tape or disk.
The distribution media usually has the
tar
command arguments you need for your system printed on the label.
If extracting from a floppy disk, the disk will contain a compressed
tar file of the C-PLOT distribution.
After extracting
the file, named
cplot.tar.Z,
you need to type the commands
zcat cplot.tar.Z | tar xvf -
You can then remove the
cplot.tar.Z
file.
(If
zcat
is
not available on your system, contact Certified Scientific Software
for assistance.)
You need to make
/usr/cplot/bin
(or
$CPLOTHOME/bin)
part of your
path (or
PATH) environment variable so that
UNIX
shell programs can find C-PLOT.
One
way to do this is by adding
set path=(/usr/cplot/bin $path)
to your
.login
file if you use
/bin/csh
or
PATH=/usr/cplot/bin:$PATH
to your
.profile
file if you use
/bin/sh.
