Check the Data Usage on Linux

Common scripts

Check the global data usage:

df -h

Check the usage of the current directory:

du -sh .

List the usages of each subdirectory under the current directory:

du -h --max-depth=1

Sort the usages of subdirectories:

du -h --max-depth=1 | sort -hr

Docker caches

When you run docker build to build an image, it stores the cache into the disk, making the storage almost full. To ease the problem, you can use the prune command to clean up the caches.

1. Remove all unused images, containers, networks, and dangling build caches:

   docker system prune

2. Remove all unused (not just dangling) images, containers, networks, and build caches:

   docker system prune -a

3. Clean up the build cache:

   docker builder prune

node_modules

find . -name "node_modules" -type d -prune -print | xargs rm -rf
