how do I use the grep --include option for multiple file types?

Question

When I want to grep all the html files in some directory, I do the following

grep --include=\"*.html\" pattern -R /some/path

which works well. T

Answer 1

Use grep with find command

find /some/path -name '*.html' -o -name '*.htm' -o -name '*.php' -type f 
 -exec grep PATTERN {} \+

You can use -regex and -regextype options too.
