[macfoxx]

Hi folks!
I try to extract some informations from sendmail log, but I have a problem.
This is the input file records:
Date Time MessageID1 person1@domain1.pl
Date Time MessageID2 person2@domain2.pl
Date Time MessageID3 person3@domain3.pl,person4@domain3.pl
Date Time MessageID4 person5@domain1.pl
Date Time MessageID5 person6@domain1.pl,person1@domain1.pl

I need to divied this lines that contains 2 or more email address in separate lines to get such output:
Date Time MessageID1 person1@domain1.pl
Date Time MessageID2 person2@domain2.pl
Date Time MessageID3 person3@domain3.pl
Date Time MessageID3 person4@domain3.pl
Date Time MessageID4 person5@domain1.pl
Date Time MessageID5 person6@domain1.pl
Date Time MessageID5 person1@domain1.pl

How I can make it in awk?

Hi

awk '$NF~/,/{n=split($NF,a,/,/);for(i=1;i<=n;i++){$NF=a[i];print}next}1' /input/file

Tested with [tt]gawk[/tt].
