'-p' option is no longer supported but documentation still references this option

[JeffKorpaTDY]

Hello.

The manpage for jacksum contains the following:

        > jacksum -a crc32 -X -f -p -r -F "#FILENAME #CHECKSUM" -o list.sfv *
        prints CRC-32 values in the Simple File Verificator (SFV) format

In version 3 of jacksum, the '-p' option is no longer present.

Suggest updating documentation to indicate that the '-p' option corresponds to older versions of jacksum (e.g. 1.7).

Hello JeffKorpaTDY,

good catch, thank you for the report!

Yes, the '-p' in the manpage is wrong, I will correct it.

version 3 of Jacksum was a major release, and all compatibility changes have been documented in the release notes.

From the section "Compatibility changes/deletions" of the release notes:

• "options -m, -p, -S, -w have been removed"

and from the section "Compatibility changes/changes" of the release notes:

• by default, recursively operation is active for folders, by default depth is unlimited
• if -r is specificed explicitly, also a depth has to be specified

So the correct example would be:

jacksum -a crc32 -X -f -F "#FILENAME #CHECKSUM" -o list.sfv *

or in Jacksum 3 and later:

jacksum --style sfv -f -o list.sfv *

BTW, sfv is a historic format, and since it has some limitations by design, it should be used for compatibility reasons only if required IMHO. For modern usage I recommend to use the Jacksum default style (because it is the most flexible one) or other quasi-standard styles. To see a matrix of styles that are supported by default and their features type

jacksum -h --style

Cheers,
