Is there a way to find out if a .js file is using jquery sintax?

I have several .js files (kinda long files), and I would like to know if there is a way to scan those files and find out if there is any jquery syntax present.

Regards,

  • Terminal/command line: 

    for file in *.js;
  do
    grep "\$(\|jQuery(" $file;
  done;

    This will search all JS files in the present directory and return any actual occurrence of jQuery's telltale "$(" OR non-aliased instance of jQuery(. You can use a regex for more specific selectors if you want.

    This will return the filename instead of the code (make sure there are no spaces in the filename).

    for file in *.js
  do
    if grep -q "\$(\|jQuery(" $file;
    then echo "$file likely uses jQuery";
    fi
  done

    Single line: 

    for file in *.js; do if grep -q "\$(\|jQuery(" $file; then echo "$file likely uses jQuery"; fi; done;

    Note that this doesn't account for any other libraries or languages that may use $and could have false positives if your JS includes something like "Bob loves money $(money!)," which clearly isn't jQuery at all. But, at least it will still flag all the files for you to check...
