Cool S#!t in Linux: Screen Recording to a gif

In my previous Cool S#!t in Linux post, I showed a recording of my terminal running the mentioned script and program. Just making that gif is a pretty cool skill, so I figured I'd explain how I did that with a bonus post.

What I did was sudo apt-get install byzanz. To figure out which arguments were necessary, I used byzanz-record --help, which provides the following options:

crow@TDalton:~$ byzanz-record --help  
byzanz-record [OPTION...] record your current desktop session

Help Options:  
  -?, --help               Show help options  
  --help-all               Show all help options  
  --help-gtk               Show GTK+ Options  

Application Options:
  -d, --duration=SECS      Duration of animation (default: 10 seconds)
  -e, --exec=COMMAND       Command to execute and time
  --delay=SECS             Delay before start (default: 1 second)
  -c, --cursor             Record mouse cursor
  -a, --audio              Record audio
  -x, --x=PIXEL            X coordinate of rectangle to record
  -y, --y=PIXEL            Y coordinate of rectangle to record
  -w, --width=PIXEL        Width of recording rectangle
  -h, --height=PIXEL       Height of recording rectangle
  -v, --verbose            Be verbose
  --display=DISPLAY        X display to use

Unfortunately, I have to do a bit of Kentucky aiming to get on target:

byzanz-record -x 0 -y 25 -w 100 -h 100 -d 1 ./file.gif byzanz-record -x 0 -y 25 -w 110 -h 110 -d 1 ./file.gif byzanz-record -x 0 -y 25 -w 200 -h 200 -d 1 ./file.gif byzanz-record -x 0 -y 25 -w 180 -h 180 -d 1 ./file.gif

I'm sure there's a tool to make this much easier but I didn't feel like looking right now. I'll update this in the future with my findings.

These commands made a 1 second gif at /home/crow/file.gif, so I pointed my web browser there- file:///home/crow/file.gif- and refreshed on each gif creation to get a look at where I was hitting.

Once I hit the area I was looking for, it was showtime. A more invested gif maker would find something to edit the length after recording or increase the quality or add titles to it, but this took two minutes to find and effectively use. I'm erring on the side of convenience.
