UNSQUASHFS(1) uncompress squashfs filesystems UNSQUASHFS(1)NAMEunsquashfs - tool to uncompress squashfs filesystems
SYNOPSISunsquashfs [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
1Mbytes (default block size 128K).
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
-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 fragment 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]
treat extract names as POSIX regular expressions rather than use
the default shell wildcard expansion (globbing).
-s[tat]
display filesystem superblock information.
-v[ersion]
print version, license and copyright information.
