Hashes?

[Dan Sladden]

From the docs:

--hashes ALGO

Records the chained hash of each transaction in a Hash metadata value, according to the hashing algorithm given by the ALGO argument (at the moment, only sha512 is supported). 

But when I run ledger --hashes I get
Error: Illegal option --hashes

ledger --version  gives me

Ledger 3.3.2-20230330, the command-line accounting tool
without support for gpg encrypted journals and with Python support

--hashes sounds really useful to avoid unintended corruption in my ~6Mb of ledger files. What's the easiest way to get hold of a version of ledger that supports them on Ubuntu 22.04 please?

Thanks

Dan

Do you not need to pass an algorithm to use for the hashing, e.g.

ledger --hashes sha512

?

I get the same response to ledger --hashes sha512 as I do to ledger --hashes :

Error: Illegal option --hashes

Looking at the documentation (info document) for ledger that I actually
have on my system, which is not the same as that in the link you gave,
there is no mention of the --hashes option.

20230330 is before the --hashes work was merged to master on
2024/Aug/05: https://github.com/ledger/ledger/pull/2300

I'd suggest putting your Ledgers in version control [e.g. Git] as the
fastest path to improving file integrity.

The --hashes option (which does take the algorithm as an argument) was added
to the code base on Nov 22, 2023. I don’t believe it’s been released under an
official tag yet.
