If there is a record delimiter, use it! Read the file record by record, and output only those that contain the wanted ID:
#!/usr/bin/perl use warnings; use strict; { local $/ = "==========\n"; while (<DATA>) { print "$/$_" if /ID: 3$/m; } } __DATA__ ========== Name: blah ID: 2 ========== Name: blah ID: 2 ========== Name: here ID: 3 ========== Name: blah ID: 2 ==========

    Would that work if there were multiple instances of ID: 3?
      Why don't you try it?


      A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James

      Hi bluesplay106,
      You wouldn't break a thing by trying out the solution you have been given by choroba. Change some of the ID given in that solution to 3 and try it out.

      If you tell me, I'll forget.
      If you show me, I'll remember.
      if you involve me, I'll understand.
