I usually have multiple Bash tabs open in Terminal, and I needed a quick way to see what each tab contained. The following bash script will set the Title of the tab.
#!/bin/bash
# Sets the title of the Terminal Window / Tab.
# title foo => Sets the title of the Terminal Window / Tab to foo.
echo -n -e "\033]0;$1\007"
I borrowed this book from the library, but before I finished it I bought it, I liked it that much. In short, I very much agree with this recommendation.
There is also transmission (actually the first one mentioned) "Between people who are in close contact with one another (within about 6 feet)"--this does not mention liquid droplets at all, which is why I figured it to be airborne.
