Count the number of occurrences of a string using sed?

Answer 1

just one gawk command will do. Don't use grep -c because it only counts line with "title" in it, regardless of how many "title"s there are in the line.

$ more file
#         title
#  title
one
two
#title
title title
three
title junk title
title
four
fivetitlesixtitle
last

$ awk '!/^#.*title/{m=gsub("title","");total+=m}END{print "total: "total}' file
total: 7

if you just want "title" as the first string, use "==" instead of ~

awk '$1 == "title"{++c}END{print c}' file
