4. TeXing

TeX and LaTeX are identical to their VMS counterparts---only quicker :-), but the tools to handle the .dvi and .ps files are superior:

• to run a TeX file through TeX, do as usual: tex file.tex;
• to turn a .dvi file into a .ps file, type dvips -o filename.ps filename.dvi;
• to visualize a .dvi file, type within an X session: xdvi filename.dvi &. Click on the page to magnify. This program is smart: if you edit and run TeX producing newer versions of the .dvi file, xdvi will update it automatically;
• to visualize a .ps file, type within an X session: ghostview filename.ps &. Click on the page to magnify. The whole document or selected pages can be printed. A newer and better program is gv.
• to print the .ps: usually the command lpr mypaper.ps will do, but if the PostScript printer is called, say, `ps' (ask your sysadm) you'll do: lpr -Pps mypaper.ps. For more information about print queues, go to Section Print Queues.
