Most command line programs accept parameters like --help
(originally from Unix) or /?
(originally from Windows) that list their common options. latex
(namely, pdftex
, which is latex
these days) is not an exception and recognizes --help
. The same applies to other TeX engines like xetex
or luatex
.
On Unix, you can also type man pdftex
etc. to read these programs' manual pages. MikTeX has them online; and TeX Live has the man pages in PDF format on your computer.
Modern TeX distributions (e.g. MiKTeX and TeX Live) have a texdoc
command line tool. You can use
texdoc pdflatex
to get the document of pdflatex
. Similarly, you can use texdoc --help
or even texdoc texdoc
to get help of the texdoc
tool.
latex --help
for a list of options and a short explanation.
