md5sum

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

• Calculate the MD5 checksum for a file:

md5sum {{path/to/file}}

• 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}}

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

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}}
