# 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`
