NTFSCMP(8) System Manager's Manual NTFSCMP(8)
NAME
ntfscmp - compare two NTFS filesystems and tell the differences
SYNOPSIS
ntfscmp [OPTIONS] DEVICE1 DEVICE2
DESCRIPTION
The ntfscmp program makes a comparison between two NTFS filesystems from all aspects and reports all variances it finds. The filesystems
can be on block devices or images files. Ntfscmp can be used for volume verification however its primary purpose was to be an efficient
development tool, used to quickly locate, identify and check the correctness of the metadata changes made to NTFS.
If one is interested only in the NTFS metadata changes then it could be useful to compare the metadata images created by using the --meta-
data option of ntfsclone(8) to eliminate the usually uninteresting timestamp changes.
The terse output of ntfscmp is intentional because the provided information is enough in each case to determine the exact differences. This
can be achieved, for instance, if one compares the verbose outputs of ntfsinfo(8) for each reported inodes by the diff(1) utility.
OPTIONS
Below is a summary of the options that ntfscmp accepts.
-P, --no-progress-bar
Don't show progress bars.
-v, --verbose
More informational output.
-h, --help
Display help and exit.
EXIT CODES
The exit code is 0 on success, non-zero otherwise.
KNOWN ISSUES
No problem is known. If you would find otherwise then please send your report to the development team: linux-ntfs-dev@lists.sourceforge.net
