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 64K.
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 constrained block device/memory systems (e.g.
embedded systems) where low overhead is needed.
print version, licence and copyright information.
-d PATHNAME, -dest PATHNAME
unsquash to PATHNAME, default "squashfs-root".
don't display the progress bar.
don't extract xattrs in file system.
extract xattrs in file system (default).
-p NUMBER, -processors NUMBER
use NUMBER processors. By default will use number of processors available.
print files as they are unsquashed.
print files as they are unsquashed with file attributes (like ls -l output).
list filesystem, but don't unsquash.
list filesystem with file attributes (like ls -l output), 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).
