in reply to Looking for a string from a huge log file

it keeps on printing the same string for all the other ID's

It is hard to imagine how a program that only has two print statements, one to STDOUT and one to a file, outside any loop "keeps on printing". Can you clarify?

[Corion]: Cosmic37: Ah, see perlfaq4, about How do I compute the intersection of two arrays
[Cosmic37]: I am out of practice; I use Perl for scientific programming for number crunching
[Corion]: Cosmic37: Basically, you read one file into a hash, keyed by your key, and then match the lines from the second file to that hash
[Cosmic37]: note that the two files only have datetimes which may match whereas other data per line is different format in file1 and file2 - is that really intersection?
[jedikaiti]: Hi Monks
[Corion]: Cosmic37: Well, if you want to use only parts of a line for the key, see split or whatever other mechanism to extract the key from the line
[Corion]: Hi jedikaiti!
[Cosmic37]: is there a webpage for full CB for this chat rather than side panel chat?
[Cosmic37]: thank you for advice
