Shell Programming and Scripting

echo a,b,c,d,e,f,g,h,i | awk 'NR>5 && $1~/f/ {print "yes"}' RS=,

I guest $5~/f/ { print $0 } would print the record if the fifth column has f in it.

I am going to assume that with "after 5th comma" you mean that letter "f" should be in the 6th (comma separated) column, not in column 7 or 8. In that case I would try this:

Code:

grep -E '^([^,]*,){5}[^,]*f' file

Or should it be an exact match in column 6?

Code:

grep -E '^([^,]*,){5}f(,|$)' file

In both cases this could be done easier using awk:

Code:

awk -F, '$6~/f/' file

and

Code:

awk -F, '$6=="f"' file

respectively

@paresh n doshi, you cannot really use RS here because you will get into trouble if there is more than 1 line, because it would then also match the pattern in the lower columns...

OP request is: Is there any way to check string is after 5th comma?
So it could be other filed than just $6, it could be $7, $8 etc.
