This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:
| # 1) Create your private key (any password will do, we remove it below) | |
| $ cd ~/.ssh | |
| $ openssl genrsa -des3 -out server.orig.key 2048 | |
| # 2) Remove the password | |
| $ openssl rsa -in server.orig.key -out server.key |
