LaTex is not available on the SGI's, xtex is not available on Linux.
LATEX, pronounced ''Lah-Tech'', is a document preparation system that is much more powerful than nroff-troff . To use it, you will definitely need a LATEX manual. You create/edit your LATEX document with either VI or EMACS, following the document syntax as described in the LATEX manual, and name the file with a .tex extension. To view or print the document, you must first 'compile' the file with the .tex extension using the latex command:
latex <documentname>
Successful compilation will produce a file with the same name as your original document, but with a .dvi extension. This stands for 'device independent file' and is the form required for viewing the document with a program called xtex. To use xtex with the dvi file enter:
xtex <documentname>
The .dvi extension will be assumed, and a document view window will be created which shows your document as it would appear if printed on a laser printer.
To print a LATEX document one more step is required. The .dvi file created by latex must be converted to a PostScript file that can be output on a laser printer. To do this, use the dvips command:
dvips -o <outdocumentname.ps> <indocumentname.dvi>
The outdocumentname.ps file can then be printed using the printing procedures described later in this manual.
To view a PostScript file run ghostview <document.ps>.
On the SGI's use:
xpsview <filename>
