IntegrityChecker java (icj): 'verify' command
To 'verify', the items to be verified must have previously seen an update operation in order to record the hash value. Verification should be regularly performed on backups, as well as originals before backup.
The verify command performs full checks:
- Checks file contents against the validation info by hashing all files.
- Flags new files
- Flags files that have changed size and/or date.
- Flags missing files and folders.
Any number and combination of volumes or folders can be specified in a single invocation.
icj verify [<path>]*
Lines starting with "#" are comments.
