NAME

rdsquashfs - tool to examine or uncompress SquashFS filesystems

SYNOPSIS

rdsquashfs [ OPTIONS ] <squashfs-file>

DESCRIPTION

View or extract the contents of a squashfs image.

The following options can be used to specify what operation to perform. One of those has to be present:
--list , -l <path>

Produce a directory listing similar to ls -l for a given path in the SquashFS image.

--cat , -c <path>

If the specified path is a regular file in the image, extract it and dump its contents to stdout.

--xattr , -x <path>

If the inode that the specified path resolves to has extended attributes, dump them as key value pairs to stdout.

--unpack-path , -u <path>

Unpack the specified sub directory from the image. To unpack everything, simply specify /.

--describe , -d

Produce a file listing from the image compatible with the format consumed by gensquashfs.

--stat , -s <path>

Dump all available information about the inode that the path refers to, including SquashFS specific internals such as the on-disk layout of a file or the fast lookup index stored in an extended directory inode.

The following options can be used to control the behaviour of the specified operation:
--unpack-root , -p <path>

If used with --unpack-path , this is where the data is unpacked to. If used with --describe , this is used as a prefix for the input path of regular files.

--no-dev , -D

Skip device special files when parsing the filesystem tree.

--no-sock , -S

Skip socket files when parsing the filesystem tree.

--no-fifo , -F

Skip named pipes when parsing the filesystem tree.

--no-slink , -L

Skip symbolic links when parsing the filesystem tree.

--no-empty-dir , -E

Skip empty directories, including ones that are empty after applying the above rules.

The following options are specific to unpacking files from a SquashFS image to disk:
--no-sparse , -Z

Do not create sparse files. Always unpack sparse files by writing blocks of zeros to disk.

--set-xattr , -X

Set the extended attributes from the SquashFS image.

--set-times , -T

Set the create and modify timestamps of the file to the mtime from the SquashFS image.

--chmod , -C

Change permission flags of unpacked files to those stored in the SquashFS image.

--chown , -O

Change ownership of unpacked files to the UID/GID set in the SquashFS image.

--quiet , -q

Do not print out progress while unpacking.

Other options:
--help , -h

Print help text and exit.

--version , -V

Print version information and exit.
