.TH MKSQUASHFS 1 "2020\-05\-12" "4.4" "create and append squashfs filesystems"
.SH NAME
mksquashfs \- tool to create and append to squashfs filesystems
.SH SYNOPSIS
\fBmksquashfs\fR \fISOURCE\fR [\fISOURCE2\fR \fI...\fR] \fIDESTINATION\fR [\fIOPTIONS\fR]
.SH 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.
.PP
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.
.SH OPTIONS
.SS Filesystem build options
.IP "\-comp \fICOMPRESSION\fR" 4
select \fICOMPRESSION\fR compression. Compressors available: gzip (default), lzma (no kernel support), lzo, lz4 and xz.
.IP "\-b \fIBLOCK_SIZE\fR"
set data block to \fIBLOCK_SIZE\fR. Default 131072 bytes. Optionally K or M can be used as a suffix to specify kilobytes or megabytes, respectively.
.IP "\-no\-exports" 4
don't make the filesystem exportable via NFS.
.IP "\-no\-sparse" 4
don't detect sparse files.
.IP "\-no\-xattrs" 4
don't store extended attributes.
.IP "\-xattrs" 4

make all files owned by root.
.IP "\-force\-uid uid" 4
set all file uids to uid.
.IP "\-force\-gid gid" 4
set all file gids to gid.
.IP "\-nopad" 4
do not pad filesystem to a multiple of 4K.
.IP "\-keep\-as\-directory" 4
if one source directory is specified, create a root directory containing that directory, rather than the contents of the directory.
.IP "\-all\-time time"
32 bit integer indicating seconds since the epoch (1970\-01\-01) used for the timestamp for all files. The SOURCE_DATE_EPOCH environment variable can also be used.
.SS Filesystem filter options

Add pseudo file definition.
.IP "\-pf \fIPSEUDO_FILE\fR" 4
Add list of pseudo file definitions.
.IP "\-sort \fISORT_FILE\fR" 4

.IP "\-wildcards" 4

.SS Filesystem append options
.IP "\-noappend" 4
do not append to existing filesystem.
.IP "\-root\-becomes \fINAME\fR" 4
when appending source files/directories, make the original root become a subdirectory in the new root called \fINAME\fR, rather than adding the new source items to the original root.
.SS Mksquashfs runtime options:
.IP "\-version" 4
print version, licence and copyright message.
.IP "\-exit\-on\-error" 4
treat normally ignored errors as fatal.

Use \fINUMBER\fR processors. By default will use number of processors available.
.IP "\-mem \fISIZE\fR" 4
