Sample text

Suppose you type dare instead of date and press the Return key before you realize your error. ), the shell displays the following error message: $ dare -bash: dare: command not found Don’t be too concerned about getting error messages. Sometimes you’ll get an error even if it appears that you typed the command correctly. This can be caused by acci‐ dentally typing control characters that are invisible on the screen. Once the prompt returns, simply reenter your command. As mentioned earlier, you can recall previous commands and edit command lines.

To change your login shell, you can either use the Unix chsh command (enter chsh on the command line and you’ll be asked which shell you’d like, starting the next time you log in) or just change the shell setting in the Terminal Preferences, as shown ear‐ lier, in Figure 2-2.

If you type Control-D at a shell prompt, it quits your shell. Depending on your preferences, your Terminal window will either close or sit there, which is generally useless, until you manually close the window. Ending Your Session To end a Unix session, you must exit the shell. You should not end a session just by quitting the Terminal application or closing the Terminal window. It’s possible that you might have started a process running in the background (see Chapter 7), and closing the window could therefore interrupt the process so it won’t complete—or, worse, leave a program running stray, without a parent shell or terminal.
