checksum.cr v0.1.4
checksum
checksum
makes the output of md5sum -c
or sha256sum -c
prettier.
Installation
You can download pre-compiled binaries from GitHub Release.
To compile from source code, follow the steps below:
git clone https://github.com/kojix2/checksum.cr
cd checksum
shards build --release
cp bin/checksum /usr/local/bin/
Usage
To verify checksums from a file, use the following command:
checksum -c md5sum.txt
Usage: checksum [options]
-c, --check FILE Read checksums from the FILE (required)
-a, --algorithm ALGORITHM (md5|sha1|sha256|sha512) [auto]
-A, --absolute Output absolute path [false]
-v, --verbose Verbose mode for outputting checksums and errors.
--no-clear Do not clear the line [false]
--no-color Do not use color [false]
--debug Debug mode [false]
-h, --help Show this message
--version Show version
To generate checksums and save them to a file, use:
checksum -a md5 * | tee md5.txt
Example output:

3be217b6d3ac7c38e1805b01b1be0178 README.md

c680044745baa4b423450c9ecb8baebb shard.yml
Then, you can verify the checksums with:
checksum -c md5.txt
Example output:
4 files in md5.txt
4 files, 4 success, 0 mismatch, 0 errors (0.0 seconds)
Experimental multi-threading support (preview)
This feature is experimental. The limitation on the speed of checksum computation is often I/O. Therefore, achieving parallelism is not the main focus.
To use this feature, compile and run with the following commands:
git clone https://github.com/kojix2/checksum.cr
cd checksum
shards build --release -Dpreview_mt
cp bin/checksum /usr/local/bin/
CRYSTAL_WORKERS=2 checksum -c md5sum.txt
