How do I find out what inotify watches have been registered?

The following terminal command worked perfectly for me on my Ubuntu 16.04 Machine:

for foo in /proc/\*/fd/*; do readlink -f $foo; done |grep inotify |cut -d/ -f3 |xargs -I '{}' -- ps --no-headers -o '%p %U %a' -p '{}' |uniq -c |sort -n

My problem was that I had a good majority of my HDD loaded as a folder in Sublime Text. Between /opt/sublime_text/plugin_host 8992 and /opt/sublime_text/sublime_text, Sublime had 18 instances of inotify while the rest of my programs were all between 1-3.

Since I was doing Ionic Mobile App development I reduced the number of instances by 5 by adding the large Node.js folder "node_modules" to the ignore list in the Sublime settings.

"folder_exclude_patterns": [".svn", ".git", ".hg", "CVS", "node_modules"]
