Computing file hashes

The following command computes the SHA256 file hashes for all of the files in a directory or directories:

# diagnose sys filesystem hash <paths> -d [depth]

<paths>	Add up to 25 paths to show only the hash for the files at those paths.
-d [depth]	Specify the maximum depth of the traversal.

This command can be used for troubleshooting and debugging the system. The file hashes of system files can be compared against known good system files to help identify any compromises made on the system files.

To hash all filesystems:

# diagnose sys filesystem hash

To hash specific filesystem, add the name of the filesystem:

# diagnose  sys  filesystem  hash  /sbin
Hash contents: /sbin

Filesystem hash complete. Hashed 1 files.

To hash multiple filesystems, add the names of the filesystems:

Up to 25 file systems can be added.

# diagnose sys filesystem hash /sbin /bin

To specify the maximum depth of the traversal:

# diagnose sys filesystem hash /data2 -d 1
