I think it might be natural for me to read the file
line by line and get the return position looks like
these(just an example), similar to do the word search
in microsoft Word, which is what I really want:
match in line

Hi Shashi,
Thanks for the reply.
Sorry I didn't make myself clear enough in the

Hi all,
Here is my problem:

Do you mean that you only want the first match, or that you only want
the word "chen" when it's not preceeded or followed by other characters?
You can use \b (word boundary) to make sure you got the whole word.
$string =~ /\b(chen)\b/g;
