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
           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
