Can I search for multiple keywords?

Yes, you can search for multiple keywords using grep with the -E option, which allows for extended regular expressions. Here's how to do it:

Example:

To filter ls -R output for multiple keywords, you can use:

ls -R | grep -E "keyword1|keyword2"

Explanation:

• -E: Enables extended regular expressions.
• "keyword1|keyword2": The pipe | acts as a logical OR, allowing you to search for either keyword1 or keyword2.

Example Usage:

If you want to find files that contain either "report" or "summary":

ls -R | grep -E "report|summary"

This will display all files and directories that include either "report" or "summary" in their names.
