# verisum
[](https://github.com/kojix2/verisum/actions/workflows/test.yml)
`verisum` makes the output of `md5sum -c` or `sha256sum -c` prettier.
Verifying MD5 of 100,000 images from "[たっぷり素材PIXTA](https://www.sourcenext.com/product/pixta/)"
## Installation
You can download pre-compiled binaries from [GitHub Release](https://github.com/kojix2/verisum.cr/releases).
To compile from source code, follow the steps below:
```sh
git clone https://github.com/kojix2/verisum
cd verisum
shards build --release
sudo cp bin/verisum /usr/local/bin/
```
Homebrew:
```
brew install kojix2/brew/verisum
```
## Usage
```
Options;
-c, --calc Compute checksums
-a, --algorithm ALGORITHM (md5|sha1|sha256|sha512)
-A, --absolute Output absolute path [false]
-v, --verbose Output checksums and errors, etc [false]
-C, --color WHEN when to use color (auto|always|never) [auto]
-D, --debug Print a backtrace on error
-h, --help Show this message
-V, --version Show version
```
### Verification
To verify the checksums with:
```sh
verisum md5.txt
```
Example output:
```
4 files in md5.txt
4 files, 4 success, 0 mismatch, 0 errors (0.0 seconds)
```
### Calculation
We recommend using standard Unix commands for calculations,
but if standard Unix commands are not available,
you can also use this tool for calculations.
**Note that the effect of the `-c` option is the opposite of `md5sum`.**
```sh
verisum -c -a md5 * | tee md5.txt
```
Sort the file list before calculating the checksums:
```sh
find . -type f | sort | xargs verisum -c -a md5 | tee md5.txt
```
Example output:
