发生了什么事TMP环境变量？ [英] What happened to the TMP environment variable?

问题描述

我总是听说找一个UNIX机器上的临时文件夹的正确方法是看TMP环境变量。当写code，在Windows上工作以及Linux，我会检查TEMP和TMP。

I always heard that the proper way to find the temporary folder on a UNIX machine was to look at the TMP environment variable. When writing code that worked on Windows as well as Linux, I would check for TEMP and TMP.

今天，我发现我的Ubuntu安装不具有环境变量都没有。

Today, I discovered that my Ubuntu install does not have that environment variable at all.

我知道这似乎你总是可以指望上的/ tmp在那里把你的临时文件，但我明白，TMP的样子，用户可以告诉你把临时文件别的地方。

I know it seems you can always count on /tmp being there to put your temporary files in, but I understood that TMP was the way the user could tell you to put the temporary files someplace else.

现在仍然是这样吗？

推荐答案

您可能会想的<一个href=\"http://www.opengroup.org/onlinepubs/000095399/basedefs/xbd_chap08.html\"><$c$c>TMPDIR.

You are probably thinking of TMPDIR.

此变量应当重新present一个目录用于需要的地方创建临时文件的程序提供一个路径。

This variable shall represent a pathname of a directory made available for programs that need a place to create temporary files.
