  用法：

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， CAB，ARJ，GZIP, BZIP2，TAR，CPIO, RPM和DEB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！

NAME

      7-Zip - 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 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)
