# 7z(1)

7-Zip file archiver with a high compression ratio

## 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

- \--

  \[Extra options for Zip format\]:\
   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
