verify command
Summary
Verifies the file
Description
If you've previously calculated the hash sum of a file using the supported algorithms, and you have the expected hash or file that contains the hashes list, you can use this command to verify the sanity of the file.
It can handle three types:
It can verify files by comparing expected hash with the actual hash.
It can verify files by opening the hashes file that
sumfiles
generated and finding the hash of the file.It can verify files by opening the hashes file that some other tool generated and finding the hash of the file, assuming that it's in this format:
<expected hash> <file name>
If the hashes match, that means that the file is not corrupted. However, if they don't match, the file is corrupted and must be redownloaded.
If you run across a hash file that verify
can't parse, feel free to post an issue or make a PR.
Command usage
verify <algorithm> <calculatedhash> <hashfile/expectedhash> <file>
