Like most applications, Terminal has a Preferences command. You use it, among other things, to switch from bash to a different shell. (Turn on “Execute this command” and then type /bin/bash for bash, or /bin/csh for tsch. Then open a new Terminal window.)
However, you’ll access most of Terminal’s settings from the Terminal→Window Settings command instead; the Terminal Inspector window opens. If you spend endless hours staring at the Terminal screen, as most Unix junkies do, you’ll eventually be grateful for the preference settings that let you control how Terminal looks and acts.
Most of the options here are self-explanatory, but here are a few worth noting.
When you choose Terminal→Window Settings, the Terminal Inspector window appears (Figure 15-8).
Changes you make in the Terminal Inspector window affect only the active window, so you can change each open window independently. Clicking Use Settings as Default, on the other hand, applies the changes to the active window and all subsequent Terminal windows you open.
