Search keywords inside of directories and files

Ruby
1

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

Sorry it should be filename, mode …this way is the correct.
f=File.new(“myfile.txt”,"w)

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.
