Sometimes we may want to grep for some words, and because the line is too long, sometimes even the whole file on one single line if it is a generated file, we may only want to see some characters before and after the match.

In that case, we can use something like:

grep-o-E'.{30}theword.{30}' somefile.html

or

curl https://somewebsite.com |grep-o-E'.{30}theword.{30}'

The-E says to treat it like it is egrep, and-o means only output the matched characters but not the whole line.
