Terragrunt creates a .terragrunt-cache folder in the current working directory as its scratch directory. It downloads your remote OpenTofu/Terraform configurations into this folder, runs your OpenTofu/Terraform commands in this folder, and any modules and providers those commands download also get stored in this folder. You can safely delete this folder any time and Terragrunt will recreate it as necessary.
If you need to clean up a lot of these folders (e.g., after terragrunt run-all apply), you can use the following commands on Mac and Linux:
Recursively find all the .terragrunt-cache folders that are children of the current folder:
find . -type d -name ".terragrunt-cache"
If you are ABSOLUTELY SURE you want to delete all the folders that come up in the previous command, you can recursively delete all of them as follows:
find . -type d -name ".terragrunt-cache" -prune -exec rm -rf {} \;
Also consider setting the TERRAGRUNT_DOWNLOAD environment variable if you wish to place the cache directories somewhere else.
