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 


创建360kb大小的分卷压缩包 
无对应命令 
Winrar a -v360 test 


带子目录信息解压缩文件 
Wzunzip test -d 
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 
Wzunzip test -f 
Winrar x test -f 


解压缩现有文件的更新文件及新文件 
Wzunzip test -n 
Winrar x test -u 


批量解压缩文件 
Wzunzip *.zip 
WinRAR e *.rar
