Info

-name: This helps to search the file nameIf we were to look for all readme files in the project, the previous command format is not helpful. Weneed to issue a case insensitive find. For demonstration purposes, we will also create a readme.mdfile:touch lib/readme.mdWe will also use the -iname argument for case insensitive search:find . -iname readme.md
You see here that both readme.md and README.md have been found. Now, if we were to search for allJavaScript files we would use:find . -name "*.js"And as you can see, there are quite a few results. For narrowing down our results, let's limit the findto the default_app folder:find default_app -name "*.js"
