Prune Command

The dnvm prune command removes older SDK versions from tracked channels to help manage disk space.

Usage

dnvm prune

How It Works

The prune command only removes SDKs that were installed through tracked channels. It will never remove:

  • SDKs installed manually using dnvm install <version>
  • SDKs restored from global.json files using dnvm restore
  • SDKs from untracked channels

Within each tracked channel, SDKs are grouped by major.minor version (e.g., 8.0.x, 8.1.x). Only the newest patch version in each group is kept.

Examples

# Track the 8.0 channel and update multiple times
dnvm track 8.0
dnvm update  # Installs 8.0.100
dnvm update  # Later installs 8.0.101
dnvm update  # Later installs 8.0.102

# Before prune: 8.0.100, 8.0.101, 8.0.102 (all from 8.0 channel)
dnvm prune
# After prune: 8.0.102 (only the latest remains)
# Mixed installation sources
dnvm track 8.0
dnvm update           # Installs 8.0.100 (tracked channel)
dnvm install 8.0.101  # Manual install
dnvm update           # Installs 8.0.102 (tracked channel)

dnvm prune
# After prune: 8.0.101 (manual), 8.0.102 (latest from channel)
# Note: 8.0.100 removed, 8.0.101 preserved (manual install)
