问题描述
我遇到的大多数系统都具有tempfile(1)和mktemp(1).有句法上的区别，mktemp也可以创建目录，但是否则它们似乎做相同的事情.
Most systems I've encountered have both tempfile(1) and mktemp(1). There are syntactic differences, and mktemp can also create directories, but they otherwise seem to do the same thing.
两者之间有区别吗?为什么两者都存在?一个比另一个更标准吗?如果我只想安全地创建一个临时文件，是否有理由比另一个优先?
Is there any difference between the two? Why do both exist? Is one more standard than the other? If I just want to create a temporary file safely, is there any reason to prefer one over the other?
我怀疑这背后有一些有趣的Unix知识，但是我的搜索没有任何结果.
I suspect there's some interesting Unix lore behind this, but my searches turn up nothing.
推荐答案
mktemp的历史记录可以追溯到.但是，它很晚才成为GNU coreutils的一部分. 此帖子宣布为coreutils包含mktemp.
The history of mktemp can be traced to OpenBSD 2.1. However, it became a part of GNU coreutils much later. This post announced the inclusion of mktemp for coreutils.
直到那时，许多程序都在使用tempfile.还有一个提案可以使tempfile围绕mktemp，已被拒绝以阻止使用tempfile.
Until then, tempfile was being used by a number of programs. There was also a proposal to make tempfile a wrapper around mktemp, which was rejected to discourage use of tempfile.
但是，以下内容已添加到tempfile手册中:
However, the following was added to tempfile manual:
