问题描述
在bash中，以下命令打开套接字
In bash the following command open a socket
exec 3<>/dev/tcp/192.168.1.200/8080
该命令在灰烬中不起作用.灰该命令是否等效?
In the ash this command does not work. Are there an equivalent of this command for ash?
在ash中命令输出错误之后:
here after the output error of the command in ash:
-ash: can't create /dev/tcp/192.168.1.200/8080: nonexistent directory
推荐答案
不，没有.标准POSIX bourne shell不提供此功能.
No, there is not. The standard POSIX bourne shell doesn't offer this feature.
顺便说一句，这个bash功能非常奇怪，因为它假装有一个名为/dev/tcp 的目录，该目录实际上并不存在.
This bash feature is very strange by the way, considering that it pretends that there is a directory called /dev/tcp which does not actually exist.
