NAME
7z - 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), 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.

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 (see
/usr/share/doc/p7zip-full/DOCS/MANUAL/switches/method.htm for a list of
methods)

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

-o{Directory}
Set Output directory

Because my friends and I
use
DOS
WIN
Linux
until today
we sent
picture like
pic.zip
and save them in ZIP Files.
It is or it was much better
then
send pic.jpg.
