Grep all the files that end with a particular extension and also contain a particular string

Question

I have some .sh and .bat files in a directory. I want to list only the .sh files that has the word "JAVA_HOME".

I tried grep -rl "JAVA_HOME" | grep "*.sh", grep -rl "JAVA_HOME" *.sh and few other random things, but none of them worked. Can someone help me with this? Thank you.

Since you appear to be using GNU grep already (with -r), add the --include option to search only those matching filenames:

grep -rl --include='*.sh' "JAVA_HOME"
