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 con-
strained 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

-ll, -lls

-e EXTRACT_FILE, -ef EXTRACT_FILE

-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
