Batch install dependencies in all subfolder-organised projects

As a lecturer ICT I have to correct the work our students make. Therefor I collect all solutions and put them in a subfolder-organised structure on disk: per student I create a subfolder and put their solution into that folder(*).

$ tree -L 1
├── student1
├── student2
├── ...
└── studentN

As – from the 2nd year on – most of our projects use some sort of dependency manager I often found myself manually cding into folders and running the command to install the dependencies.

Today I knocked up a one-liner to install all PHP dependencies (using Composer) in subfolder-organised projects. My first attempt was pretty awful, yet with a hint by Frank I eventually cleaned it up:

find . -name composer.json -maxdepth 2 -execdir composer install \;

With some minor modifications the command can also be used to installing dependencies using npm:

find . -name package.json -maxdepth 2 -execdir npm install \;

(*) actually, a handy app created by a colleague of mine bash script I wrote does this automatically for me, but that’s not the gist of this post

Did this help you out? Like what you see?
