Printing a man page

As I'll eventually get tagged to present a “Man Page of the Month” at the MonadLUG meetings, I thought I'd study a bit in advance when I found one I needed. 'top' seemed like a good candidate. But the man page is extensive, exhaustive, cross-referenced and difficult to read. So, I thought I'd print it out to scratch some notes in the margin and see if I could boil it down to a simple one-page quick reference. But how to print a man page? Well, you Google it, of course. The answer I found gave me the links I needed, even though their page neglected to display the key pipe symbols. Here's the trick:

zcat is a synonym to gunzip to pull the man page out of the .gz where it's stored. groff -man -Tps formats a file using the 'man' macro and outputs Type PostScript. Open the .ps file with the editor of your choice, and print it, convert it to PDF or whatever. So the entire command is:

zcat /usr/share/man/man1/top.1.gz| groff -man -Tps>

CentraLUG, November 6: Digital Forensic File Carving Techniques

The monthly meeting of CentraLUG, the Concord/Central NH GNHLUG chapter, happens the first Monday of (most) months on the New Hampshire Institute Campus starting at 7 PM.

Directions and maps are available on the NHTI site. This month, we’ll be meeting in the Library/Learning Center/Bookstore, room 146, marked as “I” on that map. The main meeting starts at 7 PM, and we finish by 9 PM. Open to the public. Tell your friends.

For November’s meeting, Andy Bair will present “Digital Forensic File Carving Techniques.” Data carving techniques are used during digital forensic investigations and existing file carving tools typically produce many false positives. This briefing describes new tools and techniques used by the winning team of the the 2006 File Carving Challenge held at the 6th Annual Digital Forensic Research Workshop (DFRWS). The current briefing is also located here.

In December, Tim Lind of Computerborough will present TrixBox, the Linux distro for running the Asterisk PBX software, formerly known as “Asterisk @ Home.”

January’s meeting falls on the first, so we’ll likely skip the month’s meeting. However, stay tuned for some exciting meetings coming up in 2007! More details on the group and directions to the meeting at
