Checks the files in the source against a SUM file.
Checks that hashsums of source files match the SUM file. It compares hashes (MD5, SHA1, etc) and logs a report of files which don't match. It doesn't alter the file system.
If you supply the
--download flag, it will download the data from remote
and calculate the contents hash on the fly. This can be useful for remotes
that don't support hashes or if you really want to check all the data.
Note that hash values in the SUM file are treated as case insensitive.
If you supply the
--one-way flag, it will only check that files in
the source match the files in the destination, not the other way
around. This means that extra files in the destination that are not in
the source will not be detected.
--error flags write paths, one per line, to the file name (or
stdout if it is
-) supplied. What they write is described in the
help below. For example
--differ will write all paths which are
present on both the source and destination but different.
--combined flag will write a file (or stdout) which contains all
file paths with a symbol and then a space and then the path to tell
you what happened to it. These are reminiscent of diff files.
= pathmeans path was found in source and destination and was identical
- pathmeans path was missing on the source, so only in the destination
+ pathmeans path was missing on the destination, so only in the source
* pathmeans path was present in source and destination but different.
! pathmeans there was an error reading or hashing the source or dest.
