　熟悉cisco IOS命令的人都知道我们一般对flash进行操作常用的命令是dir, cd, delete, mkdir, rmdir, erase, format等。此时，如果采用rmdir命令直接删除目录由于目录不为空是不能成功删除的。

　　switch#rmdir flash:

　　Remove directory filename [/c2960-lanbase-mz.122-35.SE5/html/]?

　　Delete flash:/c2960-lanbase-mz.122-35.SE5/html/? [confirm]

　　%Error Removing dir flash:/c2960-lanbase-mz.122-35.SE5/html/(Directory not empty)

　　如果进入目录采用delete命令一个文件一个文件的删除又太麻烦。此时我们可采用如下的命令实现快速删除一个不为空的目录。

　　switch#delete /recursive /force flash:/c2960-lanbase-mz.122-35.SE5

　　/recursive 删除指定文件夹下的所有文件和子文件夹

　　/force 删除而不给出提示

　　删除完成后，别忘了采用dir去验证一下。

删除第二个flash

升级tar固件示例

拷贝升级包到flash

1
copy tftp://192.168.1.2/c2960s-universalk9-tar.152-2.E5.tar flash

image-20210730141104508

删除旧空间

1
delete /force /recursive flash:c2960s-universalk9-mz.122-55.SE7

解压新固件

1
archive tar /xtract c2960s-universalk9-tar.152-2.E5.tar flash:

image-20210730141602772

以上最终以交换机空间不足，升级失败，下面这条命令成功

1
archive download-sw /overwrite /reload  tftp://192.168.1.2/c2960s-universalk9-tar.152-2.E5.tar
