       7-Zip - A file archiver with highest compression ratio

       7zr [adeltux] [-] [SWITCH] <ARCHIVE_NAME> <ARGUMENTS>...

       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.

       7zr  is	a  stand-alone executable. 7zr handles less archive formats than 7z, but does not
       need any others. 7zr is a "light-version" of 7za that only handles 7z archives.

       x      eXtract with full paths

	      Include archives

	      eXclude archives

       -bd    Disable percentage indicator

	      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')

	      Set Compression Method

	      7z format only : enables or disables archive header encryption (Default : off)

	      Set Output directory

	      Set Password

	      Recurse  subdirectories (CAUTION: this flag does not do what you think, avoid using

	      Create SFX archive

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

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

       -slt   Sets technical mode for l (list) command

	      Create volumes

	      Update options

	      Set Working directory

	      Exclude filenames

       -y     Assume Yes on all queries

       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 | 7zr a -si directory.tar.7z
	- to restore your backup : 7zr 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 : 7zr 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

       7zr 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

	      lzma method

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

	      number of fast bytes for LZMA = 64

	      dictionary size = 32 megabytes

       -ms=on solid archive = on

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

       7zr 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)
