zsh is needed for the script to run. The script prints open watches in the node_modules
directory, as well as the process that opened the watch. awk here filters for the
processes that are watching a node_modules directory. tac reverses the line order,
so that the line containing the process name is printed last instead of first for easy reading.
- First ensure that no processes are already watching anything in this directory (e.g. file explorer, VSCode, etc.); otherwise they will appear in the output of the script below, and you should take that into account.
npm inpx jest --watchzsh processes_with_watches.sh | awk -v RS= -v ORS='\n\n' '/node_modules\//' | tac
Observe that the jest process maintains watches in node_modules files despite
it being blacklisted in the watchPathIgnorePatterns configuration option in package.json.
