| #!/bin/sh | |
| find ./src -type f -print0 | sort -z | xargs -0 shasum | shasum |
Use LC_ALL=C sort -z if you want consistent sort order across different locales/environment settings.
@YourMJK - good call! i guess this is better:
#!/bin/sh
find ./src -type f -print0 | LC_ALL=C sort -z | xargs -0 shasum | shasum
Stumbled across this while doing some benchmarks for a Rust crate I wrote to hash directories.
If a package installation isn't too much, give paq a try.
@gregl83 - nice! thanks for adding this link / sharing your project. it looks pretty cool (and i like the explanation in the "how it works" section).
@skratchdot np, maybe it's helpful for another person!
There are trade-offs. The original solution should work on nix systems without requiring additional packages.
You might consider explicitly using SHA256 in your shasum invocations.
