Linux下的解壓軟體7zip

←手機掃碼閱讀     火星人 @ 2014-03-09 , reply:0

1.)下載安裝7z軟體(for linux

#wget -c http://sourceforge.net/projects/p7zip/files/p7zip/9.20.1/p7zip_9.20.1_x86_linux_bin.tar.bz2/download

#tar jxvf p7zip_9.20.1_x86_linux_bin.tar.bz2

cd /p7zip_9.20.1

#install.sh

###安裝完成,可以使用了

個人實驗:

可以解壓tar.bz2壓縮包,但是要解壓兩次(兩次7z x *.tar.bz2 7z x *.tar)

支持

7z(即執行LZMA壓縮演算法),ZIP,RAR,CAB,ARJ,GZIP, BZIP2,TAR,

CPIO, RPMDEB格式

2.)解壓7z壓縮的文件

7z x *.7z

3.)壓縮文件(用密碼加密)

7z a -p123456 test.7z /home/erico/test/

4.)解壓帶密碼的壓縮文件

7z x -p123456 test.7z

5.)刪除壓縮包里的文件

7z d -p123456 test.7z

#(該命令會把test.7z裡面的文件全部刪除,只保留test.7z這個空包文件)

6.)壓縮固定大小的包(分包)

7z a -p123456 -v1m test.7z /home/erico/test/

#(該命令行會將test目錄打包成多個包,每個包大小都是1M,最后一個包<=1m)

7.)解壓分包

7z x -p123456 -o/home/test_dir/ test.7z.001

# (該命令會將解壓出來的文件放到/home/test_dir/目錄下,注意,解壓分包時一定要解壓第一個分包【test.7z.001】!)

8.)保持文件目錄路徑和文件許可權

一定要用root用戶對目錄壓縮和解壓,要不目錄和文件的許可權會改變!

9.)看7zman 7z)的官方說明.

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 algo-
rithm), ZIP, CAB, ARJ, GZIP, BZIP2, TAR, CPIO, RPM and DEB for-
mats. 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/local/share/doc/p7zip/DOCS/MAN-
UAL/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

-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: % echo foo | 7z a dummy -tgzip
-si -so > /dev/null)

-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 simi-
lar)

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/MacOS/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 : "direc-
tory/*" 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


-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 archive 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)
