- Calculate the MD5 checksum for a file:
`md5sum {{path/to/file}}`
2016-01-20 11:45:42 +00:00
- Calculate MD5 checksums for multiple files:
`md5sum {{path/to/file1}} {{path/to/filen2}}`
- Calculate a MD5 checksum from the standard input:
`echo "{{text}}" | md5sum`
- Read a file of MD5SUMs and verify all files have matching checksums:
`md5sum --check {{path/to/file.md5}}`
2020-10-28 17:46:25 +00:00
- Only show a message for missing files or when verification fails:
2020-10-28 17:46:25 +00:00
`md5sum --check --quiet {{path/to/file.md5}}`
- Only show a message for files for which verification fails, ignoring missing files:
`md5sum --ignore-missing --check --quiet {{path/to/file.md5}}`
