hi,
puts 'raja(dklfjdfldjkfd)gopalan(fdf)'.gsub(/(\(.*\))/, 'raja')
this gives the output "rajaraja"
But I would like to have the output like raja raja gopalan(fdf)
could you please guide me how to write the regular expression for this?

This gives the output you said you wanted:
puts 'raja(dklfjdfldjkfd)gopalan(fdf)'.sub(/(\(\w*?\))/, ' raja ')
raja raja gopalan(fdf)

hi Joel Pearson
Thank you . It works. I designed like
puts 'raja(dklfjdfldjkfd)gopalan(fdf)'.sub(/(\(\.*?\))/, ' raja ')
But it's not working, where is the problem?

This is a great time to practice your String comparison skills. Your
Regexp is not the same as mine. Spot the difference.

hi
puts "line1 (SS13864619). line1 (SS13864619), line3
(02).".sub(/(\(\w*?\))(.*)(\(\w*?\))/, '\1\2')
it gives the output "line1 (SS13864619). line1 (SS13864619), line3 ."
But I would like to have the output
line1 (SS13864619). line1 , line3 (02)
could you please guide me how to do that?

When you're using Regexp to solve a problem, there's usually more than
one input-output scenario, so you can establish a set of rules. If
there's only one scenario then you don't need Regexp.

Yes you are right, but my problem is, each and every time the numbers
inside the bracket would vary, So I need regular expression for
that,isn't it?

If that's all that varies:
irb(main):009:0> s.sub(/(\Aline1 \(SS\d+\)\. line1 )(\(SS\d+\))/, '\1')
=> "line1 (SS13864619). line1 , line3 (02)."

line1 (SS13864619) must have been removed. Output would be,
line1 , line3 (02).
