description

7-Zip is a file archiver with the highest compression ratio. The program supports 7z (that implements LZMA compression algorithm), LZMA2, XZ, ZIP, Zip64, CAB, RAR (if the non-free p7zip-rar package is installed), ARJ, GZIP, BZIP2, TAR, CPIO, RPM, ISO, most filesystem images 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. 7zr is a "light-version" of 7za that only handles 7z archives.

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/MacOS/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 "directory/.profile")

diagnostics

7-Zip returns the following exit codes:

Normal (no errors or warnings detected)

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

Fatal error

Bad command line parameters

Not enough memory for operation

255

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

example 1

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

-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

7zr a -sfx archive.exe dir1

add all files from directory "dir1" to SFX archive archive.exe (Remark : SFX archive MUST end with ".exe")

example 3

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)
