SYNOPSIS

10       unsquashfs [OPTIONS] FILESYSTEM [directories or files to extract]
11

DESCRIPTION

14       Squashfs is a highly compressed read-only filesystem for Linux. It uses
15       zlib compression to compress both files, inodes and directories. Inodes
16       in the system are very small and all blocks are packed to minimize data
17       overhead. Block sizes greater than 4K are supported up to a maximum  of
18       64K.
19
20       Squashfs is intended for general read-only filesystem use, for archival
21       use (i.e. in cases where a .tar.gz file  may  be  used),  and  in  con‐
22       strained  block device/memory systems (e.g. embedded systems) where low
23       overhead is needed.

41
42       -p NUMBER, -processors NUMBER
43           use NUMBER processors. By default will  use  number  of  processors
44           available.
45
46       -i, -info
47           print files as they are unsquashed.
48
49       -li, -linfo
50           print files as they are unsquashed with file attributes (like ls -l
51           output).
52
53       -l, -ls
54           list filesystem, but don't unsquash.
55
56       -ll, -lls
57           list filesystem with file attributes (like ls -l output), but don't
58           unsquash.
59
60       -f, -force
61           if file already exists then overwrite.
62
63       -s, -stat
64           display filesystem superblock information.
65
66       -e EXTRACT_FILE, -ef EXTRACT_FILE
67           list of directories or files to extract. One per line.
68
69       -da SIZE, -data-queue SIZE
70           Set data queue to SIZE Mbytes. Default 256 Mbytes.
71
72       -fr SIZE, -frag-queue SIZE
73           Set fragment queue to SIZE Mbytes. Default 256 Mbytes.
74
75       -r, -regex
76           treat  extract  names  as POSIX regular expressions rather than use
77           the default shell wildcard expansion (globbing).
