1·No such file or directory?

没有这样的文件或目录？

2·Execute the code twice in succession. The second run prints the line No such file or directory, confirming that the Shared memory has been deleted.

连续执行代码两次，第二次执行会显示“ No such file or directory ”，这证明共享内存已经被删除了。

3·For example, a system call returning with Err#2 ENOENT (No such file or directory) would indicate that the command is expecting to find a file or directory but can't and subsequently fails.

例如，如果一个系统调用返回 Err#2 ENOENT（没有这样的文件或目录），就表示此命令要寻找一个文件或目录，但是无法找到，因此运行失败。

4·This is why I'm such a strong advocate of installing single-file executables (no accessory dynamic libraries, and so on), or images that unpack themselves into a single directory.

我强烈建议安装单文件的可执行文件(无附加动态库之类)或者那些将其本身解包至单个目录下的映像，其原因就在于此。
