unsquashfs [OPTIONS] FILESYSTEM [directories or files to extract]
Squashfs is a highly compressed read-only filesystem for Linux. It uses
zlib compression to compress both files, inodes and directories. Inodes
in the system are very small and all blocks are packed to minimize data
overhead. Block sizes greater than 4K are supported up to a maximum of
Squashfs is intended for general read-only filesystem use, for archival
use (i.e. in cases where a .tar.gz file may be used), and in con‐
strained block device/memory systems (e.g. embedded systems) where low
overhead is needed.
print version, licence and copyright information.
-d PATHNAME, -dest PATH
unsquash to PATHNAME, default “squashfs-root”.

use NUMBER processors. By default will use number of processors

print files as they are unsquashed with file attributes (like ls -l
list filesystem, but don’t unsquash.

if file already exists then overwrite.
display filesystem superblock information.
-e EXTRACT_FILE, -ef EXTRACT_FILE
list of directories or files to extract. One per line.
-da SIZE, -data-queue SIZE
Set data queue to SIZE Mbytes. Default 256 Mbytes.
-fr SIZE, -frag-queue SIZE
Set fragment queue to SIZE Mbytes. Default 256 Mbytes.
treat extract names as POSIX regular expressions rather than use
the default shell wildcard expansion (globbing).
