File Checksum

Tests Status

Generate checksums for files.

This program will generate checksums for either a single file, or all the files in a directory.


cargo install --path .

File Checkksum can also be installed with binaries provided with each release here.



  • Arguments:

    • <CHECKSUM_PATH> Path to the directory or file for which to generate checksums
  • Options:

    • -o, --output-file <OUTPUT_FILE> Path to the file to same the checksums. Must be a .txt file. If no path is provided the output will be printed to the screen and not saved
    • -c, --checksum-type <CHECKSUM_TYPE> The type of checksum to generate. [default: sha256] [possible values: md5, sha1, sha256]
    • --overwrite Overwrite the output file rather than appending to it
    • -v, --verbose Provides more output while running
    • -h, --help Print help


If we have the files my_file_1.xml and my_file_2.xml in the home/my_files directory, checksums can be generated for the files by running:

checksum /home/my_files -o /home/checksums.txt

The will create a file called checksums.txt in the /home directory containing the following information (hashes made up for example purposes)

sha256 checksum: e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855 - my_file_1.xml
sha256 checksum: e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855 - my_file_2.xml

Subsequent runs pointing to the same output file will append the results to the file so checksums from different directores can be save to the same file. Passing the --overwrite flag will clear the contents of the file before writing instead of appending to the file.
