Man page

Regular usage is just man followed by the name of the command you want to know about.

man ls

Really Useful: You can use -t to format the output of man as paginated postscript and pipe the results to ps2pdf to make a PDF file!

man -t ls | ps2pdf - > ls.pdf

manpdf

Hard to remember the commands for making a PDF? So create a bash script that's in your path (for instance ~/bin/manpdf),

with:

#!/bin/bash
man -t $1 | ps2pdf - > $1.pdf

And be sure to chmod +x it so that you can then use it anytime you want to generate a PDF for intensive consulation.

For example:

manpdf mplayer

to create mplayer.pdf
