Full Discussion: awk Group By and count string occurrences
Top Forums Shell Programming and Scripting awk Group By and count string occurrences Post 302841841 by Jotne on Thursday 8th of August 2013 04:25:48 AM

If it does not find any hit it will print a blank filed " "
To prevent this add a zero so it prints 0 when nothing found.
Removing the +0 gives:
Code:
a,b,c,4,2
c,d,e,5,
b,c,d,3,1

vs
Code:
a,b,c,4,2
c,d,e,5,0
b,c,d,3,1
