Top Forums Shell Programming and Scripting extract words from txt using perl Post 302381288 by durden_tyler on Thursday 17th of December 2009 05:25:48 PM

If you are a beginner, then the problem, in its entirety, may look daunting. Break it up into small pieces and work on them individually.

(1) First, connect to the MySQL database from Perl using DBI.
(2) Run the query and store the results - either in a file or better still, in a hash (if memory isn't an issue or if there aren't too many words).
(3) Next, open the text file and loop through each word.
(4) Check if the word is a hash key. If it is, print the word to stdout or to a file.

Hope these suggestions will at least get you started.
