Basics

  • Here is a page dedicated to basic UNIX commands and simple exercises to help you learn them.
  • pico - The editor for pine. I have the help file on line.
  • emacs - A better but more complicated editor. To get help once inside emacs type "ESC-x help-with-tutorial" to get a good tutorial. It does take quite a while though.

    C Compiler

  • To compile the file source.c type : gcc source.c -o source
  • To compile a program that needs math.h then use : gcc -lm source.c -o source
