Subject: Single Line replacement in file

Hi All,

My code:

code.rb

lines=File.open("hi.txt","r")
output=[]
lines.each do |single|
    out1=single.split(' ')
    out2=out1[0].gsub('<B>', '')
    out3= out2.gsub('</B>', '')
    out4=out3.gsub('<WBR>','')
    output << out4  # I need to overwrite the appropriate line.
  end

hi.txt:

wordpress.com/tag/<B>jazzez</B>/ - 11k -
swik.net/<B>jazzez</B> - 40k -
raveendran.wordpress.com/category/<B>jazzez</B>/ - 15k -
www.linkedin.com/pub/2/377/3A2 - 10k -
www.bebo.com/Profile.jsp?MemberId=4902204778 -


My need:

code.rb --> out contains my proper output. But i didn't able to
overwrite the same line in file.It means
1. single --> "wordpress.com/tag/<B>jazzez</B>/ - 11k - "
2. out4 --> "wordpress.com/tag/jazzez"

Here i want to replace the first line in hi.txt file 1 to 2.


Awaiting your reply
