in the some code bock (html), if "some code" has special chars included such as "<", ">", they will be resolved as HTML tags.

< is usually encoded with < and > is usually encoded as >. You can also use < >.

You can run a sed command to replace. For example:

sed "s/</\&lt;/g" to replace all occurrences of < with <. You can also specify line numbers to replace in sed so sed "3,5s/</\&lt;/g" would replace all occurrences of < with < between lines 3-5. The -i option may be useful if you're dealing with files.
