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 minimise 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

-da[ta-queue] size
Set data queue to size Mbytes. Default 256 Mbytes.
-d[est] pathname
unsquash to pathname, default "squashfs-root".
-e[f] extract file
list of directories or files to extract. One per line.
-f[orce]
if file already exists then overwrite.
-fr[ag-queue] size
Set fagment queue to size Mbytes. Default 256 Mbytes.
-i[nfo]
print files as they are unsquashed.
-li[nfo]
print files as they are unsquashed with file attributes (like ls -l output).
-ll[s]
list filesystem with file attributes (like ls -l output), but don't unsquash.
-l[s]
list filesystem, but don't unsquash.
-n[o-progress]
don't display the progress bar.
-p[rocessors] number
use number processors. By default will use number of processors available.
-r[egex]
