 Some of the key command-line options supported by `fromfile` are:
-* `-o/--output-signatures` will save generated signatures to any of the [standard supported output formats](command-line.md#saving-signatures-more-generally).
+* `-o/--output-signatures` will save generated signatures to any of the [standard supported output formats](command-line.md#choosing-signature-output-formats).
 * `-o/--output-csv-info` will save a CSV file of input filenames and parameter strings for use with the `sourmash sketch` command line; this can be used to construct signatures in parallel.
 * `--already-done` will take a list of existing signatures/databases to check against; signatures with matching names and parameter strings will not be rebuilt.
 * `--output-manifest-matching` will output a manifest of already-existing signatures, which can then be used with `sourmash sig cat` to collate signatures across databases; see [using manifests](command-line.md#using-manifests-to-explicitly-refer-to-collections-of-files). (This provides [`sourmash sig check` functionality](command-line.md#sourmash-signature-check---compare-picklists-and-manifests) in `sketch fromfile`.)
