md5sum: Only show a message when verification fails, ignoring missing files.

md5sum

$ md5sum --ignore-missing --check --quiet ${filename-md5}

try on your machine

This command uses the md5sum tool to check the integrity of files using MD5 checksums. Let's break down each component of the command:

md5sum: This is the command to calculate the MD5 checksum of files.
--ignore-missing: This flag tells md5sum to ignore any missing files. If a file specified in the checksum list is not found, it will not produce an error.
--check: This flag instructs md5sum to check the given checksums against the corresponding files. It reads the MD5 checksums from a file and compares them with the calculated checksums of the specified files.
--quiet: This flag suppresses the normal output of md5sum, reducing the amount of information displayed to only the checksum status. If a file matches its checksum, no output will be generated. Only errors or mismatched checksums will be shown.
${filename-md5}: This is a placeholder for the file that contains the list of MD5 checksums to check against. You need to replace it with the actual path and name of the file.

Overall, this command is used to efficiently verify the integrity of files by comparing their MD5 checksums with the ones provided in a checksum list. The --ignore-missing flag ensures that missing files do not interrupt the checking process, while --quiet reduces the output to only display errors or mismatched checksums.
