UNSQUASHFS(1)			 uncompress squashfs filesystems		    UNSQUASHFS(1)

NAME
       mksquashfs - tool to uncompress squashfs filesystems

SYNOPSIS
       unsquashfs [OPTIONS] FILESYSTEM [directories or files to extract]

DESCRIPTION
       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.

OPTIONS
       -v, -version
	   print version, licence and copyright information.

       -d PATHNAME, -dest PATHNAME
	   unsquash to PATHNAME, default "squashfs-root".

       -n, -no-progress

       -no, -no-xattrs
	   don't extract xattrs in file system.

       -x, -xattrs
	   extract xattrs in file system (default).

       -p NUMBER, -processors NUMBER
	   use NUMBER processors. By default will use number of processors available.

       -i, -info
	   print files as they are unsquashed.

       -li, -linfo
	   print files as they are unsquashed with file attributes (like ls -l output).

       -l, -ls
	   list filesystem, but don't unsquash.

       -ll, -lls
	   list filesystem with file attributes (like ls -l output), but don't unsquash.

       -f, -force
	   if file already exists then overwrite.

       -s, -stat
	   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.

       -r, -regex
	   treat extract names as POSIX regular expressions rather than  use  the  default  shell
	   wildcard expansion (globbing).

   Decompressors available
       gzip

       lzo

       xz
