使用zip命令的-d参数即可删除zip包中的特定文件。 示例：假设有test.zip，包含_code(目录)、_code.zip、readme.txt三个文件，现在要删除test.zip中的_code目录，则执行如下命令 zip -d test.zip _code zip -m myfile.zip ./rpm_info.txt 向压缩文件中myfile.zip中添加rpm_info.txt文件 from:https://www.cnblogs.com/jifeng/p/7839248.html
View Details返回上一次目录 有时候千辛万苦进入了一个很深层的目录，一不小心输入了cd并回车，有什么办法快速回到刚才所在的目录呢？对于bash来说，只需要很管理的一个命令： cd – 该命令等同于cd $OLDPWD，关于这一点在bash的手册页(可使用命令man bash访问其手册页)中有介绍：
|
1 |
An argument of - is equivalent to $OLDPWD. |
并且它还会返回上一次目录的物理路径。 from:https://www.cnblogs.com/yixius/articles/6971080.html

最后找打解决方法：
|
1 |
vi /etc/hosts.allow |
追加：
|
1 |
sshd: ALL |
重启ssh就ok了
|
1 |
service sshd restart |
