The three n commands cause the next three lines to be appended to our current pattern space buffer , and now our line looks like this
这三个n命令导致将下三行附加到当前模式空间缓冲区，现在这一行看起来如下：
The h command puts this back in the hold space for safekeeping , and d deletes the line from the pattern space so that it isn t printed
H命令将该内容放回保留空间保护起来，然后， d从模式空间删除该行，以便不打印它。
You ll also notice that we ve replaced the d command with the p command , which as you might guess , explicitly commands sed to print the pattern space
您还会注意到，我们用p命令替换了d命令，如您所猜想的那样，这明确要求sed打印模式空间。
Then , the d command is executed , which deletes " foo " from the pattern space , so it doesn t get printed after all the commands are executed for this line
然后，执行d命令，该命令从模式空间中删除" foo " ，以便在对这一行执行完所有命令之后不打印它。
This command tells sed to copy the contents of the pattern space the buffer that holds the current line being worked on to the hold space a temporary buffer
该命令告诉sed将模式空间（保存正在处理的当前行的缓冲区）的内容复制到保留空间（临时缓冲区）。
