good question. I never knew much about awk so I googled for a tutorial introduction and found these features as different:

  1. awk can take different actions on each line by use of a series of
    pattern { action } pattern { action }
    rules. C<desift> does not do different things on different lines based on the input text
  2. awk is a complete language offering flow of control, functions and more. An entire webserver has been written in awk. Here is a simple program which takes small text delimited database and tabulates the amount of each type of computer:
    { computers[$1]++ } END { for ( name in computers ) print "The number of ",name,"computers is",compu +ters[name] }
PApp::SQL and CGI::Application rock the house
