我从ruby脚本运行net share以删除Windows网络共享。
如果共享中的文件正在使用中，net share将询问用户是否要继续删除，因此我的脚本需要检查命令的输出，并写出{{1}如果它检测到Y要求输入。
为了能够写出进程，我使用访问标记net share打开它。
尝试使用"r+"写入流程时，出现错误：
IO#puts我在这里做错了什么？ （错误发生在Errno::EPIPE: Broken pipe
行）
（由net_share.puts "Y"写出的问题文字后面没有换行符，因此我使用net share来读取输出。）

如果您希望net share ... /delete命令始终成功，则可以传递/y标志：
C:\>net share foo /delete /y
Users have open files on foo. Continuing the operation will force the files closed.
foo was deleted successfully.

尝试w +而不是r +
Mode | Meaning
-----+--------------------------------------------------------
"r" | Read-only, starts at beginning of file (default mode).
-----+--------------------------------------------------------
"r+" | Read-write, starts at beginning of file.
-----+--------------------------------------------------------
"w" | Write-only, truncates existing file
| to zero length or creates a new file for writing.
-----+--------------------------------------------------------
"w+" | Read-write, truncates existing file to zero length
| or creates a new file for reading and writing.
-----+--------------------------------------------------------
"a" | Write-only, starts at end of file if file exists,
| otherwise creates a new file for writing.
-----+--------------------------------------------------------
"a+" | Read-write, starts at end of file if file exists,
| otherwise creates a new file for reading and
| writing.

使用net_share.readlines代替begin / rescue / end。
