I am searching inside of the files ,like this

unless /.\*test/.match( file\_name ) || /.\*Test/.match( file\_name )  
text = File.read(file\_name)  
text.scan(/find/) do |it|  
$files \<\< ("#{it} —\> #{File.basename(file\_name) } =====\>  
#{File.dirname(file\_name)}")  
end

I can list the keyword, file name and directory name with path name,  
but i want  
1- file name without any extension. for example : _.rb ,_.java, \*.txt ,  
…  
2- I want to output only last directory name. Not path name. for  
example: C:\test\myfiles, C:\test\outputs\ … so only I want to  
output myfiles and outputs directory names  
3- i want to output the search keyword`s left and right side sentences  
also.

please help me. please!

Pathname to the rescue:

[http://www.ruby-doc.org/stdlib/libdoc/pathname/rdoc/index.html](http://www.ruby-doc.org/stdlib/libdoc/pathname/rdoc/index.html)

Also, please look into $` (prematch) and $’ (postmatch) and / or  
MatchData and Regexp#match.

Kind regards

I suggest you look at File::split, File::basename or String.split.

I am not sure what that means. You can print the line containing a  
keyword easily with

File.open(filename){|f| f.each\_line{|l| STDOUT \<\< l if l =~  
keyword\_regexp }}

and if you want sentences you could possibly split on punctuation  
instead of newlines.

In addition, you can always use the universal hammer: split().

fname = “C:/path/to/dir/pic10.jpg”  
pieces = fname.split("/")  
puts pieces[-2] #dir

parts = pieces[-1].split(".")  
puts parts[0] #pic10

thank you very very much. That was what I want.

Yeah, I want that. I want to output some sentences, they are sql  
sentences insert, update. delete and table column names.

Thanks I will try it.

I find that I often use

fname.split(File::Separator)

to make my code more OS-agnostic…

While I’ve heard that “/” will work in Ruby code run on Windows… I  
don’t have a system to test.

Should I continue using File::Separator?
