SQFSDIFF(1) User Commands SQFSDIFF(1) NAME sqfsdiff - compare two squashfs images by contents and metadata SYNOPSIS sqfsdiff [OPTIONS...] --old <first> --new <second> DESCRIPTION Compare two squashfs images. In contrast to doing a direct diff of the im- ages, this actually parses the filesystems and generates a more meaningful difference report. If only contents are compared, any differences in packed file layout, or- dering, compression, inode meta data and so on is ignored and the two im- ages are considered equal if each directory contains the same entries, sym- link with the same paths have the same targets, device nodes the same de- vice number and files the same size and contents. A report of any difference is printed to stdout. The exit status is similar that of diff(1): 0 means equal, 1 means different, 2 means problem. Possible options: --old, -a <first> Specify the first filesystem image or source directory, relativ to which the changes are evaluated. --new, -b <second> Specify the second filesystem image to source directory to compare to the first one. --no-contents, -C Do not compare file contents. --no-owner, -O Do not compare file owners. --no-permissions, -P Do not compare permission bits. --timestamps, -T Compare file timestamps. --inode-num, -I Compare inode numbers of all files. --super, -S Also compare meta data in super blocks. --extract, -e <path> Extract files that exist in both images but have different contents to the specified directory. Contents of the first image end up in a sub directory named old and the contents of the second image in a sub directory named new. --help, -h Print help text and exit. --version, -V Print version information and exit. EXIT STATUS The exit status is similar that of diff(1): 0 means equal, 1 means differ- ent, 2 means problem. SEE ALSO rdsquashfs(1), sqfs2tar(1) AUTHOR Written by David Oberhollenzer.
