Two parseDuration functions existed with different grammars; only the one in internal/vaultik/helpers.go was reachable from a flag. The unused copy in internal/cli/duration.go is deleted, so no flag accepts anything it did not before.

The README gave 6m as the six-months example for snapshot purge --older-than, but m is minutes: that command removed every snapshot older than six minutes. The example is now 6mo, and the help for --older-than and --keep-newer-than states that m is minutes and mo is months.

The parser now rejects negative durations, which it used to accept or silently make positive.

- 2026-09-21: Collapsed the two duration parsers into one and fixed the
`--older-than` months example
([issue #123](https://git.eeqj.de/sneak/vaultik/issues/123)). Two
functions named `parseDuration` existed with different grammars;
`snapshot purge --older-than` and `--keep-newer-than` both already went
through the one in `internal/vaultik`, while the richer copy in
`internal/cli/duration.go` was reachable only from its own test. Kept
the live-path parser and deleted the unused one, so no flag's accepted
grammar changes. The trap the issue was filed over: `README.md`
documented `6m` as the months example for `--older-than`, but `m` is
minutes, so the documented command deleted every snapshot older than
six minutes on a destructive flag. Corrected the doc to `6mo` and put
both flags' help text on one example list that states `m` is minutes
and `mo` is months. The surviving parser now rejects negatives, which
it previously accepted (`-5h`) or silently made positive (`-5d`).
Table-driven tests cover every unit, `6m` as six minutes, `6mo` as 180
days, and rejection of a bare number, an unknown unit, and a negative.
