I need some help about keywords searching in directory and files.

I have a directory  
dirs–a  
|–b  
|–c  
and files  
a–\>a1.txt  
|–\>a2.txt  
|–\>a3.txt

I can lsit all files and directories like this,

require ‘find’  
dirs = [‘C:\Users\test\dirs’]  
keywords = [“keyword1”,“keyword2”]  
for dir in dirs  
Find.find(dir) do |path|  
if FileTest.directory?(path)  
if keywords.include?(File.basename(path))  
# make something here… and output the finding data  
else  
Find.prune # skip the files  
next  
end  
else  
puts path  
end  
end  
end

how can I do it and how can I print output the results in a text or csv  
file?  
Or need a plugin like Ferret?  
please help me.

To write to a file you need something like this:  
f=File.new(“w”,“myfile.txt”)  
f \<\< “line 1”  
f \<\< “line 2”  
f.close

It is OK. Thank you very much.  
I don’t want to print the whole line,  
I want to print some sql special words,  
for example;  
1- if the line start with comment(//) do not print the line.  
2- if line contain “find” and I want to print the leftside of “::” or  
class name (like this ClassBase::Class print ClassBase)  
3- if line contain “find” and I want to print the sql commands (like  
insert update …), table and column names. ( like this; insert into  
tableA where  
columnA, columnB, columnC… print he TableA and ColumnA, columnB,  
columnC　…)

please help me.
