NAME
       7-Zip - A file archiver with highest compression ratio

SYNOPSIS
       7z [adeltux] [-] [SWITCH] <ARCHIVE_NAME> <ARGUMENTS>...

DESCRIPTION
       7-Zip is a file archiver with the highest compression ratio. The program supports 7z (that
       implements LZMA compression algorithm), ZIP, CAB, ARJ, GZIP, BZIP2, TAR, CPIO, RPM and DEB
       formats. Compression ratio in the new 7z format is 30-50% better than ratio in ZIP format.

       7z uses plugins to handle archives.

FUNCTION LETTERS
       a      Add

       d      Delete

       e      Extract

       l      List

       t      Test

       u      Update

       x      eXtract with full paths

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

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

       -bd    Disable percentage indicator

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

       -l     don't  store  symlinks;  store  the  files/directories they point to (CAUTION : the
	      scanning stage can never end because of recursive symlinks like 'ln -s .. ldir')

       -m{Parameters}
	      Set Compression Method

       -mhe=on|off
	      7z format only : enables or disables archive header encryption (Default : off)

       -o{Directory}
	      Set Output directory

       -p{Password}
	      Set Password

       -r[-|0]
	      Recurse subdirectories (CAUTION: this flag does not do what you think, avoid  using
	      it)

       -sfx[{name}]
	      Create SFX archive

       -si    Read data from StdIn (eg: tar cf - directory | 7z a -si directory.tar.7z)

       -so    Write data to StdOut (eg: 7z x -so directory.tar.7z | tar xf -)

       -slt   Sets technical mode for l (list) command

       -t{Type}
	      Type of archive (7z, zip, gzip, bzip2 or tar. 7z format is default)

       -v{Size}[b|k|m|g]
	      Create volumes

       -u[-][p#][q#][r#][x#][y#][z#][!newArchiveName]
	      Update options

       -w[path]
	      Set Working directory

       -x[r[-|0]]]{@listfile|!wildcard}
	      Exclude filenames

       -y     Assume Yes on all queries

DIAGNOSTICS
       7-Zip returns the following exit codes:

	      0      Normal (no errors or warnings detected)

	      1      Warning  (Non fatal error(s)). For example, some files cannot be read during
		     compressing. So they were not compressed

	      2      Fatal error

	      7      Bad command line parameters

	      8      Not enough memory for operation

	      255    User stopped the process with control-C (or similar)

Backup and limitations
       DO NOT USE the 7-zip format for backup purpose on Linux/Unix because :
	- 7-zip does not store the owner/group of the file.

       On Linux/Unix, in order to backup directories you must use tar :
	- to backup a directory  : tar cf - directory | 7za a -si directory.tar.7z
	- to restore your backup : 7za x -so directory.tar.7z | tar xf -

       If you want to send files and directories (not the owner  of  file)  to	others	Unix/Mac-
       OS/Windows users, you can use the 7-zip format.

	 example : 7za a directory.7z  directory

       Do not use "-r" because this flag does not do what you think.

       Do  not	use  directory/*  because  of  ".*" files (example : "directory/*" does not match
       "directory/.profile")

EXAMPLE 1
       7z a -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on archive.7z dir1
	      adds all files from directory "dir1" to archive archive.7z using "ultra settings"

       -t7z   7z archive

       -m0=lzma
	      lzma method

       -mx=9  level of compression = 9 (Ultra)

       -mfb=64
	      number of fast bytes for LZMA = 64

       -md=32m
	      dictionary size = 32 megabytes

       -ms=on solid archive = on

EXAMPLE 2
       7z a -sfx archive.exe dir1
	      add all files from directory "dir1" to SFX archive archive.exe (Remark  :  SFX  ar-
	      chive MUST end with ".exe")

EXAMPLE 3
       7z a -mhe=on -pmy_password archive.7z a_directory
	      add  all	files from directory "a_directory" to the archive "archive.7z" (with data
	      and header archive encryption on)
