Obtaining DirAx
You can obtain the program via
anonymous ftp.
The program is distributed as binary in the form of a compressed tar file
for various unix platforms.
Copy the tar file into an empty directory, for example
/usr/local/src/dirax/dirax1.13.tar.Z
cd
/usr/local/src/dirax/
Uncompress with uncompress dirax1.13.tar.Z
Untar the file with the command
tar -xvf dirax1.13.tar
(If you have GNU tar, you could skip the uncompress step and use
gtar -xvfZ dirax1.13.tar.Z)
Generate with your editor a file
/usr/local/bin/dirax (or somewhere else
in your searchpath). This file should contain two lines:
#!/bin/sh
exec
/usr/local/src/dirax/dirax "$@"
Make this file executable:
chmod ugo+x /usr/local/bin/dirax
The help command will activate netscape. If netscape is not available
mozilla will be tried. You may define another browser by adding
a BROWSER alias in the file
/usr/local/src/dirax/dirax.init
(for example \alias browser mybrowser) or
define an environment variable BROWSER.
You should now be able to use dirax.
You may run the command
dirax < ex_solutions.inp > ex.out. and
compare the results with the file ex_solutions.out in the distribution.
DEC-Alpha: Some versions of netscape (e.g. version 4.7) cannot be
started from within DirAx, but DirAx will display the
documentation once netscape is running.
