Hi Guys,  
I want to download certain file types or certain files by its  
name using ruby code.  
example:  
In Shell scripting, I can say cp _.txt, which inturn copies all files  
with extension “.txt”,  
similarly i can say cp test_ , all files with the string “test” are  
copied.

I want to achieve similar tasks using ruby code, as i am novice using  
ruby.  
My purpose is that i am connecting to my Linux server through ftp and  
trying to download files with certain extension.  
Let me know if any more info is required from my end

cheers  
Thanks in Advance

Does not work with FTP directories. Rather look at Net::FTP:

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

Especially method #nlst

[http://ruby-doc.org/stdlib/libdoc/net/ftp/rdoc/classes/Net/FTP.html#M001128](http://ruby-doc.org/stdlib/libdoc/net/ftp/rdoc/classes/Net/FTP.html#M001128)

Kind regards
