If you do not tell us what you did and what error you saw we cannot
help you. Did you look at
http://www.ruby-doc.org/core/classes/Time.html#M000297 ?

Kind regards

i want attaches a timestamps to file for this i doing Time.now_filename
but it gives error because time has a space sum it so i need some
another mechanism using which i generate timestamps and attached to
timestamps.

Not sure what you are really doing, I get

$ ruby -e ‘Time.now_filename’
-e:1: undefined method `now_filename’ for Time:Class (NoMethodError)

But Pena’s solution is probably what you want. Here’s another approach:

file_name = “base_name-#{Time.now.strftime(’%Y%m%d-%H%M%S’)}”

Kind regards

pardon me if i do not get you right here, but do you want something like
this, eg?

system “dir *testing.rb”
01/31/2003 05:55 PM 4 testing.rb
1 File(s) 4 bytes
#=> true

require ‘fileutils’
#=> true

FileUtils.mv f, [Time.now.strftime(“%Y-%m-%d-%H%M%S”),f].join(“_”)
#=> 0

system “dir *testing.rb”
01/31/2003 05:55 PM 4 2008-05-07-173139_testing.rb
1 File(s) 4 bytes
#=> true
