Question

I have a data like this, fixed number of characters in every line(8)

RYRYRYRR
YRRRRYRR
YYRRRRRY
RYYRRRRR
RRRRRRRY
RYRRRRRY

I need output count the number of “Y” and “R” separately as shown below..

RYRYRYRR 3 5
YRRRRYRR 2 6
YYRRRRRY 3 5

I’ve tried a script using grep as shown below..

grep -c ‘Y’test.dat which is printing some number like 13

Answer 1

Try this:

awk '{print $0, gsub("Y", "Y"), gsub("R", "R")}'

In awk, gsub returns the number of successful substitutions.
