List Largest Files in a Backup

A backup set is growing unexpectedly and you need to rank the largest files before deleting, pruning, or changing retention.

Command

find backup -type f -printf '%s %p\n' | sort -nr | head

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 files just because they are large; confirm age, ownership, and restore value first.

Expected output

A largest-first list of backup files with byte counts.

System impact

Read-only, can be slow. Nothing changes. The command prints file sizes and paths sorted largest first.

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

Recovery / rollback: no state is changed.

When to use it

Use when backups are growing or a storage bill suddenly changes.

When not to use it

Do not delete files just because they are large; confirm age, ownership, and restore value first.

Study mapping

Use this as independent command practice: read the notes, predict the output, then compare it with the example before using a real shell.

Independent study support only. No affiliation, endorsement, exam dumps, or real exam questions.
