未解决 [求助]不在cmd下如何执行msg命令？

MSG {username | sessionname | sessionid | @filename | *}
[/SERVER:servername] [/TIME:seconds] [/V] [/W] [message]
username 标识指定的用户名。
sessionname 会话名。
sessionid 会话 ID。
@filename 识别这样一个文件，该文件含有将所发消息发送到的用户
名、会话名和会话标识号的列表。
- 给指定服务器上的所有会话发送信息。
/SERVER:servername 要联系的服务器(默认值是当前值)。
/TIME:seconds 等待接收器确认消息的时间延迟。
/V 显示有关执行的操作的信息。
/W 等待用户的响应，跟 /V 一起有用。
message 要发送的消息。如果没有指定，发出提示，或者从 stdin
读取。
OD跟到这一步基本明确了，不是cmd通讯，而是msg。
