Hi,

How to extract a portion of text from a Web page.

If we can extract using grep command, please let me know the syntax.

Are you looking to check for existence of a certain string?

this can be done with check_http with either a string match

 -s, --string=STRING
    String to expect in the content

or a regex match

 -r, --regex, --ereg=STRING
    Search page for regex STRING
