So, I am using Ubuntu 12.04.4 and I wonder if there is a program for opening PDF-files installed. I find that evince is installed in the system (by googling), and I stop to think if this can be done within Linux instead.
Using a terminal.
man -k PDF
Which does not print evince, since -k searches the NAME section in all the manuals, and the text does not mention "PDF". Fortunately, Ubuntu 12.04.4 comes with man version 2.6.1 which has the option -K --global-apropos.
man -K PDF
gives a list mentioning evince + a a lot more files since the -K forces the search to be in all the sections in the manuals.
evince is just an example. And in hindsight a better keyword is "viewer".
How shall one (in the most effective way) find what programs are installed in a Linux system that match certain keywords?
Is there another way than man (or apropos)?
