Hosting Operations

Read-only, can be slow

Exclude the Current Release from Cleanup

Several release directories exist and you need to identify stale candidates without touching the active symlink target.

Command

current=$(readlink -f /home/deploy/current); find /home/deploy/releases -mindepth 1 -maxdepth 1 -type d ! -samefile "$current" -printf '%TY-%Tm-%Td %p\n' 2>/dev/null | sort

Before you run this

System impact: Read-only. Can create load on large logs, directories, filesystems, or process tables.

When not to use it: 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

Read-only, can be slow. Nothing changes. The command resolves the active release and prints only non-current candidates.

Scope this to the smallest useful path or service on busy systems.

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.

find /var/tmp/uploads -xdev -type f -mtime +7 -printf '%TY-%Tm-%Td %10s %p\n' 2>/dev/null | sort

Rank Old Cleanup Candidates by Size

The oldest file is not always the file that buys back meaningful space.

find /var -xdev -type f -mtime +7 -printf '%s %TY-%Tm-%Td %p\n' 2>/dev/null | sort -nr | head

Review Log Files Before Cleanup

Before truncating logs, prove which log files are large and how old they are.

find /var/log -xdev -type f -printf '%10s %TY-%Tm-%Td %p\n' 2>/dev/null | sort -nr | head -50

Summarize Cache File Ages

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

find /var/cache -xdev -type f -printf '%TY-%Tm-%Td\n' 2>/dev/null | sort | uniq -c
