[SOLVED] Grep files with uncommented "console.log" string

Issue

I need to return all files in a directory which contain the string console.log uncommented. So I think I should search for any line which does not have the string // between the newline and the console.log string.

This command returns both commented and uncommented console.log. I want to exclude instances where console.log is commented.

grep -H -r  "^.*[^//].*console\.log" /var/www/vhosts/mysite.com

The command I need would match these lines:

var num = 0;  console.log(num);
alert('some text'); console.log('anything');
  console.log();

but not match these lines:

var num = 0; // console.log(num);
//alert('some text'); console.log('anything');
  // console.log();

Solution

Use -L switch

grep -rL '//.*console\.log' directory

Update:

grep -rlP '^(?!.*//.*console\.log)(?=.*console\.log)' directory
