exact string match in a word
Post 302267824 by dr_sabz on Sunday 14th of December 2008 04:45:33 AM

As this was the most logical thing to try I had already this, but it gives me a total count of all the "hello" from all of the lines.Perhaps my first email was not clear (sorry for this). Im looking for the number of occurences of the string "hello" on each line of the file.
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)

split
SPLIT(1) General Commands Manual SPLIT(1) NAME
split - split a file into pieces SYNOPSIS
split [ option ... ] [ file ] DESCRIPTION
Split reads file (standard input by default) and writes it in pieces of 1000 lines per output file. The names of the output files are xaa, xab, and so on to xzz. The options are -n Split into n-line pieces. -e expression File divisions occur at each line that matches a regular expression; see regexp(6). Multiple -e options may appear. If a subex- pression of expression is contained in parentheses (...), the output file name is the portion of the line which matches the subex- pression. -f stem Use stem instead of x in output file names. -s suffix Append suffix to names identified under -e. -x Exclude the matched input line from the output file. -i Ignore case in option -e; force output file names (excluding the suffix) to lower case.
