xdvi and
pxdvi.
Both commands are invoked from the command line in the same way as
xdvi myfile.dvior
pxdvi myfile.dviThe suffix
.dvi may be omitted so, for example, the command
pxdvi myfile will also work.
The first version, xdvi, is the more
traditional and has somewhat fewer features. In particular, there is
no way to print a dvi file from within xdvi.
The second version pxdvi has a print button allowing
you to print the entire document or some subset of pages. This makes
pxdvi a better choice as a web browser helper application for
files of type application/dvi. In addition pxdvi displays
a list of page numbers in the margin which you can click on to jump
directly to a page.
The keystroke commands for these two programs have significant
differences, especially in the page motion commands. The page motion
commands for xdvi seem ad hoc
(u for up, d for down, etc.) while those
from pxdvi seem to be copied from the vi and emacs
editors. These differences can be confusing however, as some single
commands do different things in the two versions. The complete list
for each version is given below.
