I had a font I needed to install to make some graphics for a web project. It was easy enough to buy the font – I just chose the option for the TrueType file (TTF) and I knew I’d be fine. I had a little trouble getting the font to show up though, so I record my efforts here.

1. Put the TTF files (there’s usually three) in their own subdirectory of /usr/share/fonts/truetype.
2. As root, run these two commands in the new subdirectory: mkfontscale and mkfontdir
3. Check to see if the font is installed: run xlsfonts and see if your font is there
4. If you don’t see your font, start Googling, but perhaps start here.

Sometimes you need to reinstall a Debian system. Maybe your hard drive is going pear-shaped, maybe you got a new computer, maybe you are replicating a system, maybe you are building a lab. In any case, if you want all the packages that are installed on system 1 on your new/other system 2, here’s an easy way:

1. On system 1, make a file with your installed/removed packages: dpkg --get-selections > packages.txt
2. Get a base install done on system 2, and set /etc/apt/sources.list to be the same as on system 1
3. Get packages.txt onto system 2
4. Run dpkg --set-selections < packages.txt on system 2
5. Run dselect install on system 2
6. Optional: Dance

Occasionally I put my screen session into a state that I call sulking – it refuses to take new input. This happens in two ways – one, my screen session gets fired into the background, and I left with the message [1]+ Stopped screen; the other seems to lock the screen from showing me any input. In the second state I can navigate among screen sessions, and create new instances, but not type.

After much thrashing about, I learned that when I hit C-a z (Control a, z) I put the session in the background, and it can be returned with the command fg. Similarly, if I hit C-a s I have locked the session to input, and to return it I need to hit C-a q. Good things to know.
