You may find it helpful to get an idea of how much you already know about the shell before you read the following chapters. Run the simple commands shown below and examine their output:
%more Ë/.cshrc Ë/.login
Display shell startup files (try page or pg if you don't have more) %stty all
Display terminal settings (try stty âa if stty all doesn't work) %printenv
Display environment variable values %set
Display shell variable values %alias
Display alias definitions %history
Review your history
Does the output from these commands make sense to you, or does it look like gibberish? If the latter, that's fineâtry to remember how strange some of the command results look now. As you read through this handbook, occasionally run the commands again. Their output should become more and more comprehensible and you'll get a good sense of what you're learning as recognizable landmarks begin to appear in this unfamiliar terrain.
