Summary

• Don't have to know all this to use the command line! Pick some basics and go; learn more over time.
• Main points:
  • Flexibility, saving time, ease of use (yes!)
  • A shell makes the command line
  • History substitutions re-use previous command lines
  • String expansion builds arguments
  • Command substitution uses output of one command as arguments to another
  • Using Perl/etc. from the Command Line
  • Shell Variables, Loops
  • UNIX Filters and Pipes: building blocks
  • Shell Scripts, Aliases, Functions: abbreviate command lines
  • MH does email UNIX-style
• Plenty of places for GUIs, just not every place
