On: Use the unofficial Bash strict mode

[daveloyall]

    The set -e option instructs bash to immediately exit if
    any command has a non-zero exit status. You wouldn't
    want to set this for your command-line shell,

...but, it's a great addition to your buddy's `.bashrc`. For maximum effectiveness, be physically present, perhaps with a camera. :)

Oooh, this is my new favorite. Previously it was "echo exit >> ~/.bashrc" ;)

[jasonjayr → redsymbol]

Place this entire line @ the bottom of your target's .bashrc

    echo 'sleep .1' >> ~/.bashrc

By week 2 my poor friend had conditioned himself to work within 1 session since spawning new sessions became unbearably slow :)
