        The FORMAT specifier syntax
        +++++++++++++++++++++++++++

        The ``--format`` option uses Python's `format string syntax
        <https://docs.python.org/3.10/library/string.html#formatstrings>`_.

        Examples:
        ::

            $ borg repo-list --format '{archive}{NL}'
            ArchiveFoo
            ArchiveBar
            ...

            # {VAR:NUMBER} - pad to NUMBER columns.
            # Strings are left-aligned, numbers are right-aligned.
            # Note: time columns except ``isomtime``, ``isoctime`` and ``isoatime`` cannot be padded.
            $ borg repo-list --format '{archive:36} {time} [{id}]{NL}' /path/to/repo
            ArchiveFoo                           Thu, 2021-12-09 10:22:28 [0b8e9...3b274]
