File Checksum

Generate checksums for files.

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

Installation

Install with cargo:

cargo install file-checksum

Install on Debian/Ubuntu:

curl -LO https://github.com/sanders41/python-project-generator/releases/download/v1.0.16/python-project-generator_1.0.16_amd64.deb
sudo dpkg -i python-project-generator_1.0.16_amd64.deb

file-checksum can also be installed with binaries provided with each release here.

Usage

Generate

• 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

Example

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.
