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
