# NAME

bup-validate-object-links - scan the repository for broken object links

# SYNOPSIS

bup validate-object-links

# DESCRIPTION

`bup validate-object-links` scans the objects in the repository for and reports any “broken links” it finds, i.e. any links from a tree or commit in the repository to an object that doesn’t exist. Currently, it doesn’t include “loose objects” (those not in packfiles – which git may create, but bup doesn’t), and it can’t handle tag objects (which bup also doesn’t create).

Whenever a broken link (missing reference) is found, an ASCII encoded line formatted like this will be printed to standard output:

    no MISSING_HASH for PARENT_HASH

# EXIT STATUS

The exit status will be 1 if any broken links are found, 0 if none are found, and some other positive integer for other failures.
