md5sum

Calculate MD5 cryptographic checksums. More information: https://www.gnu.org/software/coreutils/md5sum.

  • Calculate the MD5 checksum for one or more files:

md5sum {{path/to/file1 path/to/file2 ...}}

  • Calculate and save the list of MD5 checksums to a file:

md5sum {{path/to/file1 path/to/file2 ...}} > {{path/to/file.md5}}

  • Calculate an MD5 checksum from stdin:

{{command}} | md5sum

  • Read a file of MD5 checksums and filenames and verify all files have matching checksums:

md5sum --check {{path/to/file.md5}}

  • Only show a message for missing files or when verification fails:

md5sum --check --quiet {{path/to/file.md5}}

  • Only show a message when verification fails, ignoring missing files:

md5sum --ignore-missing --check --quiet {{path/to/file.md5}}

  • Check a known MD5 checksum of a file:

echo {{known_md5_checksum_of_the_file}} {{path/to/file}} | md5sum --check
