So if input file has 2 lines:
hellolaylahellolayla
hellohellohello

Then output should be:
2 ("hello" matched in line 1 twice)
3 ("hello" matched in line 2 a total of 3 times)

A count of 5 is not needed!

Cheers for any help in awk, sed or even perl (but im not very clever with perl yet)

oh thats what you want.
then its more simple try this
Code:
awk 'total=0;{ total += gsub("hello","")}{print total}' filename

Try this:

Code:
awk -F"hello" '{print NF-1}' file

Use nawk or /usr/xpg4/bin/awk on Solaris if you get errors.

Many thanks to vidyadhar85 and Franklin52. Both methods worked well giving the right output.

Vidyadhar85,
I see you reset the count to 0 when each new line begins. Lovely thankyou.

Can you give the sample input file and your desired output file?

For exact string match(no substring) -w option is used with grep. Sorry I could get your requirement.

Hi Siba,

I showed the input and output in a previous post, when I first posted my query. Here it is again:

So if input file has 2 lines:
hellolaylahellolayla
hellohellohello

Then output should be:
2 ("hello" matched in line 1 twice)
3 ("hello" matched in line 2 a total of 3 times)

If you see above, the post above the code works correct. Thank you Smilie
