Shell Programming and Scripting

Hi,

I want to add two new lines to a file.
I have:
dn: uid=beele,ou=medewerker,dc=hva,dc=nl
street: Wibautstraat 2-4

dn: uid=beelx,ou=medewerker,dc=hva,dc=nl
street: Wibautstraat 2-4

I want to make:
dn: uid=beele,ou=medewerker,dc=hva,dc=nl
changetype: modify
replace: street
street: Wibautstraat 2-4

dn: uid=beelx,ou=medewerker,dc=hva,dc=nl
changetype: modify
replace: street
street: Wibautstraat 2-4

Can i use sed to do this? I can't find a way to add a new line..

Either the i or a commands can be used in sed to add lines. Could you be more exact in describing what you want? Do you really want to add 2 lines to a file? So you start with a 10,000 line file and wind up with a 10,002 line file? I would just use an editor for that.

If you want to add many copies of a pair of lines, how do you know where to add them? Will the first line always start with "dn:"? Will the the second line always start with "street:"?

I would use awk, e.g...

Code:

awk -F: '{
   print $0;
   if ($1 == "dn") {
      print "changetype: modify";
      getline;
      print "replace: " $1;
      print $0;
   }
}' file1 > file2

Thanks Ygor, works perfectly.
Awk is still a mystery to me, but i think i'll have to learn to work with it, seems very usefull!
