If you want to work with sed on it, you can do it immediately with sed - why do you want to use grep too? — user unknown, Apr 20 '12 at 13:46

Use fgrep with -e option like this

fgrep -e 'firts_pattern' -e 'second_pattern'

If you plan to use sed you may just want to use the following. You may not need two separate commands. Using sed you can find if the two patterns exist and if so replace both of them with one command.

NOTE: The following contains an inline edit. PLEASE BACKUP YOUR FILE PRIOR TO TESTING

sed -i 's/<link type="text\/css" rel="stylesheet" href="https:\/\/test.mydomain.com\/store.css">/<REPLACE PATTERN 1>/g;s/<script type="text\/javascript" language="javascript" src="https:\/\/test.mydomain.com\/store\/gwt.nocache.js">/<REPLACE PATTERN 2>/g' /yourfile

If you are an OS X user you can try the following

NOTE: The following contains an inline edit. PLEASE BACKUP YOUR FILE PRIOR TO TESTING

sed -i '' 's/<link type="text\/css" rel="stylesheet" href="https:\/\/test.mydomain.com\/store.css">/<REPLACE PATTERN 1>/g;s/<script type="text\/javascript" language="javascript" src="https:\/\/test.mydomain.com\/store\/gwt.nocache.js">/<REPLACE PATTERN 2>/g' /yourfile

Remember to escape the '/' characters in your REPLACE PATTERN if you intend on using them.

Also you may want to try awk. In this case it functions much like grep.

awk '/<link type="text\/css" rel="stylesheet" href="https:\/\/test.mydomain.com\/store.css">/; /<script type="text\/javascript" language="javascript" src="https:\/\/test.mydomain.com\/store\/gwt.nocache.js">/' /yourfile

with egrep you don't need those parenthesis, just the pipe separating the patterns inside single quotes.

egrep -n 'pattern1|pattern2'

should work just fine.
