Clean up temporary, recovery, and corrupted files from Plex databases directory.
|
||||
|
||||
OPTIONS:
|
||||
--dry-run Show what would be removed without actually removing
|
||||
--verbose Show detailed output
|
||||
--help Show this help message
|

|

DESCRIPTION:
|
||||
This script removes:
|
||||
- Temporary files (*-tmp, *-2025-*-tmp)
|
||||
- MD5 checksum files (*.md5)
|
||||
- Recovery files (*recovery*)
|
||||
- Repaired files (*repaired*)
|
||||
- Empty backup files (*empty-backup*)
|
||||
- DBRepair.log files
|
||||
- Corrupted database directories (corrupted-*)
|
||||
|
||||
This script preserves:
|
||||
- Active database files (*.db, *.db-shm, *.db-wal)
|
||||
- Plex built-in backups (*.backup.*)
|
||||
- Legitimate dated backups (*.db.YYYYMMDD)
|
||||
- EPG databases (tv.plex.providers.epg.cloud-*.db)
|
||||
|
||||
EXAMPLES:
|
||||
$0 --dry-run # Preview what would be removed
|
||||
$0 --verbose # Remove files with detailed output
|
||||
sudo $0 # Remove files (requires root for some files)
|
