Keeping projects up to date with find scripting

I want to keep my sources up to date and in case they have Node.js package manager and/or Bower in use, install those.

This is rather trivial once certain requirements are set:

  • Source codes are synced via Git, thus directory .git is present
  • Node.js dependencies are listed in package.json
  • Bower dependencies are listed in bower.json

The examples shown below can easily be adjusted to work with other similar tools.

All the examples use the -maxdepth parameter with value 3 which means that measured from the current directory, three sub levels are searched.

Sync source code

The following one line command will look for .git directory and for those directories that under it is found, resets the state to the latest known commit, pulls all changes from the server repository, including other branch information and finally sets the currently used branch to be master.

find . -maxdepth 3 -type d -name '.git' -printf '\n%h\n' \
 -exec sh -c '(cd {}/.. && git pull --all)' ';'

Install Node.js dependencies

The following one liner installs the NPM dependencies that are listed in the package.json which is present in case the project is Node.js based.

find . -maxdepth 3 -type f -name 'package.json' -printf '\n%h\n' \
 -exec sh -c '(cd $(dirname {}) && npm install)' ';'

Install Bower dependencies

Almost exactly the same with the previous installation procedure, the Bower dependencies are installed if the directory contains a file called bower.json.

find . -maxdepth 3 -type f -name 'bower.json' -printf '\n%h\n' \
 -exec sh -c '(cd $(dirname {}) && bower install)' ';'
