Risk: safeExclude the Current Release from Cleanup
Several release directories exist and you need to identify stale candidates without touching the active symlink target.
Command
current=$(readlink -f /lab/disk-inode-cleanup/home/deploy/current); find /lab/disk-inode-cleanup/home/deploy/releases -mindepth 1 -maxdepth 1 -type d ! -samefile "$current" -printf '%TY-%Tm-%Td %p\n' | sortBefore you run this
Risk: safe. Do not delete old releases until rollback policy, backup state, and active symlinks are confirmed.
Expected output
Older release directories, excluding the current symlink target.
System impact
Nothing changes. The command resolves the active release and prints only non-current candidates.
When to use it
Use before release-directory cleanup on hosts that keep multiple deploy versions.
When not to use it
Do not delete old releases until rollback policy, backup state, and active symlinks are confirmed.
Recovery / rollback
No undo needed because the command only resolves and prints paths.

Preview Old Temp Files Before Deleting
The safe version of cleanup is a candidate list first.

Rank Old Cleanup Candidates by Size
The oldest file is not always the file that buys back meaningful space.

Review Log Files Before Cleanup
Before truncating logs, prove which log files are large and how old they are.

Summarize Cache File Ages
Cache cleanup is safer when you know whether files are stale or still active.
