# 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}}` - Read a file of MD5SUMs and verify all files have matching checksums: `md5sum -c {{path/to/file.md5}}` - Calculate a MD5 checksum from the standard input: `echo "{{text}}" | md5sum`
