    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
