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
       don't display the progress bar.

   -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
