原创 Linux操作系统 作者:junnylove 时间:2009-07-03 10:53:25 0 删除 编辑

实验环境:

系统:AS5.2 内核2.6.18-92.el5

软件:p7zip_4.48

1.)下载安装7z软件(for linux

cd /home/erico/

wget http://sourceforge.net/projects/p7zip/files/p7zip/p7zip_4.48_x86_linux_bin.tar.bz2

tar jxvf /home/erico/p7zip_4.48_x86_linux_bin.tar.bz2

cd /home/erico/p7zip_4.48

sh install.sh

###安装完成,可以使用了

 

个人实验:

可以解压tar.bz2 压缩包,但是要解压两次(两次 7z x *.tar.bz2    7z x *.tar)

 

支持7z (即执行LZMA压缩算法) ZIP  CABARJGZIP, BZIP2 TAR CPIO, RPMDEB格式

 

2.)解压7z压缩的文件

7z x  *.7z

 

3.)压缩文件(用密码加密)

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

 

4.)解压带密码的压缩文件

7z x -p123456 test.7z

 

5.)删除压缩包里的文件

7z d -p123456 test.7z

#(该命令会把test.7z里面的文件全部删除,只保留test.7z这个空包文件)

 

6.)压缩固定大小的包(分包)

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

#(该命令行会将test目录打包成多个包,每个包大小都是1M,最后一个包<=1m)

 

7.)解压分包

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

# (该命令会将解压出来的文件放到/home/test_dir/目录下,注意,解压分包时一定要解压第一个分包【test.7z.001】!)

8.)保持文件目录路径和文件权限

一定要用root用户对目录压缩和解压,要不目录和文件的权限会改变!

 

9.)看7zman 7z)的官方说明。

NAME

       7-Zip - A file archiver with highest compression ratio

 

SYNOPSIS

       7z [adeltux] [-] [SWITCH] ...

 

DESCRIPTION

       7-Zip  is  a file archiver with the highest compression ratio. The pro-

       gram 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  direc-

              tory.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 com-

                     pressed

 

              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  direc-

       tory.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  :  "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 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)
