MANIFEST User Commands NAME manifest - File System Verification Utility SYNOPSIS manifest [OPTIONS] [FILESPEC] DESCRIPTION This command lists files and the output differs from the LS or DIR command in that a Message Digest which reflects the file content is calculated from each byte in the file and displayed. The default message digest is MD5. While the digest may be useful in comparing with an externally published value the benefit in the MANIFEST command is its ability to compare against a Reference Point (RefPoint). The FILESPEC parameter is typically not used. By default MANIFEST scans the entire file system but can be directed to evaluate a single file or set of files. The -U option (see below) generates the RefPoint which retains information about each and every file on the JNIOR. This is stored in the /manifest.json file and in a second backup copy of this JSON database located in /flash. When MANIFEST is subsequently run it compares the current status of a file against the RefPoint. Differences are reported and this can go a long way in helping the user understand what is changing on the JNIOR. The following are indications MANIFEST provides when differences are detected. [New] - File did not exist before. It is new. [Modified] - File has changed. [Missing] - File existed before and is no longer found. [Corrupt] - File content has changed but the timestamp has not. The following are displayed when updating the RefPoint. [Added] - File is new and added. [Updated] - File has changed and updated. [Removed] - File no longer exists and has been removed. Options: -U Update the RefPoint. The JSON database is overwritten. -L Only list differences. -C Report CRC32 instead of MD5. -H Report SHA1 instead of MD5. -S, -R Recurse sub-directories when the FILESPEC parameter is provided. FILESPEC can include the wildcards '*' and '?'. NOTES Typical usage is to issue the MANIFEST -UL command at a point when you are confident in the status of the JNIOR. At a later time you can use the MANIFEST -L command to compare against the RefPoint. You will then know if any files have been lost or corrupted. Presumably those that are modified can be explained. Logs typically quickly become modified. You would also find out if any new files have appeared. Once satisfied you would update the RefPoint with another MANIFEST -UL.
