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
