Delete node_modules folder recursively from a specified path using command line.

Answers from StackOverflow. Click here for the whole discussion thread.
Print out a list of directories to be deleted:
find . -name 'node_modules' -type d -prune
Delete directories from the current working directory:
find . -name 'node_modules' -type d -prune -exec rm -rf '{}' +

Alternatively, you can use trash (brew install trash) for staged deletion:
find . -name node_modules -type d -prune -exec trash {} +


Another answer from StackOverflow,
find . -name 'node_modules' -type d -prune -exec rm -rf '{}' +
I found that the command would run a very long time to fetch all folders and then run a delete command, to make the command resumable I'd suggest using \; and to see progress of the command being run use -print to see the directory being deleted.
Note: You must first cd into the root directory and then run the command or instead of find . use find {project_directory}
To delete folders one by one
find . -name 'node_modules' -type d -prune -exec rm -rf '{}' \;
To delete folders one by one and printing the folder being deleted
find . -name 'node_modules' -type d -prune -print -exec rm -rf '{}' \;

Uninstall MySql on a Mac OS X

Summary

To completely uninstall MySql OS X it is neccessary to remove numerous files.

Symptom

You unable to install an older version of MySql even though you thought you have removed everything.

Resolution

To uninstall MySQL and completely remove it (including all databases) from your Mac do the following:
  • Open a terminal window
  • Use mysqldump to backup your databases to text files!
  • Stop the database server
  • sudo rm /usr/local/mysql
  • sudo rm -rf /usr/local/mysql*
  • sudo rm -rf /Library/StartupItems/MySQLCOM
  • sudo rm -rf /Library/PreferencePanes/My*
  • edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
  • rm -rf ~/Library/PreferencePanes/My*
  • sudo rm -rf /Library/Receipts/mysql*
  • sudo rm -rf /Library/Receipts/MySQL*
  • sudo rm -rf /private/var/db/receipts/*mysql*
The last three lines are particularly important as otherwise, you can't install an older version of MySQL even though you think that you've completely deleted the newer version!
