Class Notes (an evolving document)

A general recommendation: To find documentation or help, do a google search on any of the topics covered in class. For example, "gawk tutorial" will turn up several useful documents that supplement the class notes on gawk programming. The examples below under "Resources" were found this way.

Homeworks:

• Final Exam: note the new rules!
• Homework 9: Python: classes
• Homework 8: Python: random numbers, trees
• Homework 7: Python: lists, dictionaries, functions
• Homework 6: Shell and Gawk
• Homework 5: Shell and Gawk
• Homework 4: Regular expressions, Awk
  If you have a problem with entering odd characters such as tabs in emacs, use "c-q" before the character. The character "c-q" acts as a quote for a single character in emacs, like "\" in the shell. Note that in "tr" and "gawk", tabs are recognized as "\t".
• Homework 3: Bash Help
• Homework 2: HTML
• Homework 1: Emacs

Resources:

• Python:
  • A Python init file (assumes that you installed a few modules from www.python.org; use: python -i $HOME/.init.py )
  • Quick Reference
• Bash:
  • Man page
  • Reference
  • the original Intro by Bourne
• Sed:
  • Tutorial
  • Man page
• Regular expressions:
  • Tutorial (possibly old) (the original)
  • Man page
• Silly example files:
  • less.txt
  • foo.grep
  • foo.sort
• ASCII list
• Emacs initialization file: .emacs
  The file contains two keyboard macros that copy the current line to the other window in 2-window mode:
  C-x c --- copies the current line and moves to the next line
  C-x v --- copies the current line and stays on the current line
  Unfortunately, the first macro bombs if you are at the end of the file and there is no terminating .
• Bash initialization files: .bashrc and .bash_profile
• Cygwin/bash trouble: commands not found -- PATH
