Chris Morgan's bash-for-recording

README.md

A script bash-for-recording, for invocation by termrec. This does the following:

• Set the window size to 80×24
• Set HOME to a new empty directory
• Set USER and NAME to dummy values (creating an actual new throwaway user account would be better here)
• Set TERM to xterm-256color
• Clear the environment (env -i)
• Set a deliberately very simple and obvious prompt (which sets the title as well)
• Clear the screen
• Finally, start a nice clean bash profile
