tempfile和mktemp有什么区别? [英] What's the difference between tempfile and mktemp?

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.

mktemp的历史记录可以追溯到此帖子宣布为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:

在NFS分区上创建文件时，不能保证专有创建. tempfile无法建立临时目录. tempfile已过时；您应该改用mktemp(1).

Exclusive creation is not guaranteed when creating files on NFS partitions. tempfile cannot make temporary directories. tempfile is deprecated; you should use mktemp(1) instead.
