Listing files whose contains contain a string, and are of a particular extension?


I believe that the following can be used to locate files that contain the contents 'SomeString' or 'SomeOtherString':
Code:
find /home/username/public_html -type f -print0 | xargs -0 egrep -l 'SomeString|SomeOtherString'
How would I limit this to searching for the text 'SomeString' or 'SomeOtherString', but only if the file has extension .php, .inc or .js?

Also - can someone help explain details of what piping to xargs does here? I don't understand how this command actually works.

ls <pathname> | egrep '(php|inc|js)$' | xargs <...etc.(your code)..>

ls -R if you need it to drill down

Code:
find /home/username/public_html -type f -name '*.php' -o -name '*.inc' -o -name '*.js' -print0 | xargs -0 egrep -l 'SomeString|SomeOtherString'

or

find /home/username/public_html -type f -name '*.php' -o -name '*.inc' -o -name '*.js' -exec egrep -l 'SomeString|SomeOtherString' {} \;

When you
run a command then add a "| xargs command2". The results of command1 will be passed to
command2, possibly on a line−by−line basis

-print0 means null char after file name not newline as we have also given -0 option for xargs.
-l means only filename mentioned not matching content within it.
egrep means extended pattern in grep (same as grep -E)

i suggest
find . -type f | grep -i "file_extension_you_want" | egrep -i 'pattern1|pattern2'
Though not short , but more lucid.
by the way -i means ignore case
