RAR参数:

一、压缩命令

1、将temp.txt压缩为temp.rarrar a temp.rar temp.txt

2、将当前目录下所有文件压缩到temp.rarrar a temp.rar *.*

3、将当前目录下所有文件及其所有子目录压缩到temp.rarrar a temp.rar *.* -r

4、将当前目录下所有文件及其所有子目录压缩到temp.rar,并加上密码123rar a temp.rar *.* -r -p123 

二、解压命令

1、将temp.rar解压到c:\temp目录rar e temp.rar c:\temprar e *.rar c:\temp(支持批量操作)

2、将temp.rar解压到c:\temp目录,并且解压后的目录结构和temp.rar中的目录结构一 

压缩目录test及其子目录的文件内容

Wzzip test.zip test -r -P

WINRAR A test.rar test -r

 

删除压缩包中的*.txt文件

Wzzip test.zip *.txt -d

WinRAR d test.rar *.txt 

 

刷新压缩包中的文件,即添加已经存在于压缩包中但更新的文件

Wzzip test.zip test -f

Winrar f test.rar test 

 

更新压缩包中的文件,即添加已经存在于压缩包中但更新的文件以及新文件

Wzzip test.zip test -u

Winrar u test.rar test

  

移动文件到压缩包,即添加文件到压缩包后再删除被压缩的文件

Wzzip test.zip -r -P -m

Winrar m test.rar test -r

 

 添加全部 *.exe 文件到压缩文件,但排除有 a或b

开头名称的文件

Wzzip test *.exe -xf*.* -xb*.*

WinRAR a test *.exe -xf*.* -xb*.*

  

加密码进行压缩

Wzzip test.zip test

-s123。注意密码是大小写敏感的。在图形界面下打开带密码的压缩文件,会看到+号标记(附图1)。

WINRAR A test.rar test -p123

-r。注意密码是大小写敏感的。在图形界面下打开带密码的压缩文件,会看到*号标记(附图2)。

  

按名字排序、以简要方式列表显示压缩包文件

Wzzip test.zip -vbn

Rar l test.rar

  

锁定压缩包,即防止未来对压缩包的任何修改

无对应命令

Winrar k test.rar

Winrar x test -r

  

不带子目录信息解压缩文件

Wzunzip test

Winrar e test

 

解压缩文件到指定目录,如果目录不存在,自动创建

Wzunzip test newfolder

Winrar x test newfolder

  

解压缩文件并确认覆盖文件

Wzunzip test -y

Winrar x test -y

  

解压缩特定文件

Wzunzip test *.txt

Winrar x test *.txt

  

解压缩现有文件的更新文件
