推荐答案

没有直接从文件中删除行的方法。但是，您可能会逐行读取输入文件，仅将要维护的行复制到新文件。在该过程结束时丢弃原始文件并重命名新写入的文件。

There is no direct way for removing a line from a file. However you might read the input file line by line, copying to a new file only the lines you want to maintain. At the end of the process discard the original file and rename the freshly written one.
