md5sum

Calculate MD5 cryptographic checksums.

=> More information.

• 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}
