我之前理解的打字
pdflatex -interaction=nonstopmode
与在序言中使用 \nonstopmode 是一样的，而且，排版不会在发现错误时停止。显然两者都不是。即使使用上面的命令，以下 MWE 也会在错误处停止。但是，如果取消注释 \nonstopmode，则编译会像预期的那样不停地进行到最后。此外，如果将 jfm.cls 替换为 article.cls，行为也符合预期——也就是说，使用上面的命令，即使注释掉 \nonstopmode，编译也会继续到最后。
现在，jfm.cls 是一个日志类文件，可以从以下位置下载
http://arxmliv.kwarc.info/sty/jfm.cls
我还没有深入研究过这个问题。不过，这并不是重点。重点是这个类文件中的某些内容阻止了 -pdflatex interaction=nonstopmode按照宣传的方式工作，并且它的行为与在序言中放置 \nonstopmode 不同。使用 TeXlive 2017。
要么我遗漏了什么（通常如此），要么就是有什么不对劲；无论如何，这里是 MWE，任何关于正在发生的事情的建议都将受到赞赏。

Hee 是日志文件，使用pdflatex -interaction=nonstopmode test.tex我必须输入“r”才能继续编译。

它不是在标准配置中使用测试文件调用的，但如果类最终调用，\checkfonts那么它将“重新启动”（或在本例中启动）\errorstopmode
