NAME

7z - 7-Zip file archiver with a high compression ratio

SYNOPSIS

	7z	command [ switches ...] archive_name [ file_names ] [@ listfile ]
	7zz	command [ switches ...] archive_name [ file_names ] [@ listfile ]
	7za	command [ switches ...] archive_name [ file_names ] [@ listfile ]
	7zr	command [ switches ...] archive_name [ file_names ] [@ listfile ]

DESCRIPTION

7-Zip file archiver with a high compression ratio
There are some variants for 7z executable.

	7z		Full featured with plugin support
	7zz		Full featured single binary executable with no plugins support
	7za		Supports major formats only, no plugins, but smaller executable size
	7zr		Only supports LZMA codec and related formats (7z, lzma, xz), no plugins, but smallest executable size

Important Note of 7zip behavior

When used without any file_names argument, 7z implicitly uses "." for file_names . This behavior leads some unexpected result.
"a" (add) command

Recurcevily add files from current directory into archive_name file.

"d" (delete) command

Recurcively delete files from archive_name file. This means delete all files from archive_name file.

OPTIONS

Commands

	a		Add files to archive
	b		Benchmark
	d		Delete files from archive
	e		Extract files from archive (without using directory names)
	h		Calculate hash values for files
	i		Show information about supported formats
	l		List contents of archive
	rn		Rename files in archive
	t		Test integrity of archive
	u		Update files to archive
	x		eXtract files with full paths

Switches

Stop switches and @ listfile parsing

-ai[r[-|0]]{@ listfile |! wildcard }

Include archives

-ax[r[-|0]]{@ listfile |! wildcard }

eXclude archives

-ao{a|s|t|u}

set Overwrite mode

-an

disable archive_name field

-bb[0-3]

set output log level

-bd

-m{ Parameters }

set compression Method
-mmt[ N ]

set number of CPU threads

-mx[ N ]

set compression level: -mx1 (fastest) ... -mx9 (ultra)

-mcp=[ codepage number ]

[Extra options for Zip format]:
Use codepage number for file name encoding. When 7-Zip detects legacy Zip format, 7-Zip automatically choose suitable legacy codepage number by your current locale. If automatic codepage chooser fails, use this option to manually set codepage number.
(example): Use "-mcp=437" for CP437
