bug#50786: Missing info??

You don't mention what version and distribution you are using. Upstream
parted does have -l in the manpage so I'd file a bug with the
distribution.

parted now (or will, depending on whether your distribution includes
patches from master) has a --fix option for your exact problem. When
used along with --script it will automatically fix the size of the disk
and write the backup partition table.
