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: disable progress indicator

-bs{o|e|p}{0|1|2}: set output stream for output/error/progress line

-bt: show execution time statistics

-i[r[-|0]]{@listfile|!wildcard}: Include filenames

-m{Parameters} -mmt[N] -mx[N] -mcp=[codepage number]: set compression Method

set number of CPU threads

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

[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
