Re^2: grep command

That's the simple modification I told about:

$ perl -n -e '$count++ while /\bhello\b/g; END { print $count }' text.
+out

And to answer kyle at Re^2: grep command, my interpretation was that he was concerned about how many times the word happened with no concern for which particular lines. But then he tells about grepping — so if the issue is finding the lines and then telling how many times it appeared in total, this one may work:

$ perl -n -e 'print, $count++ while /\bhello\b/g; END { print $count }
+' text.out

Almost! However, the last line in which "hello" is found is printed twice. CLI: `perl -n -e "print, $count++ while /\bhello\b/g; END { print $count }" hello.out` (quotes revised for windows) file hello.txt: hello. hellow, world. bye world says hello. bye hello, hellow, hello not now. done. output `hello. hellow, world. bye world says hello. hello, hellow, hello hello, hellow, hello 4`	[reply] [d/l]

I don't see it as a simple spoiler, as people quite often try it in scalar context like `$cnt += m{pattern}g;` which doesn't work as they expect. Enjoy, Have FUN! H.Merijn	[reply] [d/l]

I don't see it as a simple spoiler, as people quite often try it in scalar context like `$cnt += m{pattern}g;` [download] But then the usual workaround is `$cnt += () = m{pattern}g;` [download] which is somewhat simpler and more natural than your reference-and-dereference trick.
