Export a man page in pdf

If groff and gropdf exists on your Linux system, you should be able to use

man -Tpdf man >man.pdf

(note the absence of a space between -T and pdf)

On an Ubuntu system, it should be enough to install the groff package to get access to gropdf.

The option argument to -T is passed on to groff and groff will use its -T option with the same option argument. So, read the groff manual about -T for more info.

On systems using mandoc, the groff utility does not need to be installed for the above command to work since the mandoc utility (called by man) would convert the manual to PDF by itself.

Make sure you have ghostscript package installed:

sudo apt-get install ghostscript

You would need to convert the postscript to the PDF; for the command last that would be:

man -t last | ps2pdf - last.pdf
