/usr/bin 中的 Python 脚本 [英] Python scripts in /usr/bin

问题描述

我正在用 python 编写一个非常基本的应用程序(目前只有一个文件).我的问题是如何获取它以便 python 脚本能够在没有 .py 扩展名的情况下在/usr/bin 中运行?

I'm writing a pretty basic application in python (it's only one file at the moment). My question is how do I get it so the python script is able to be run in /usr/bin without the .py extension?

例如，而不是运行

python htswap.py args

从当前所在的目录，我希望能够 cd 到任何目录并执行

from the directory where it currently is, I want to be able to cd to any directory and do

htswap args

提前致谢！

推荐答案

只需通过重命名文件去除 .py 扩展名.然后，您必须将以下行放在文件顶部:

Simply strip off the .py extension by renaming the file. Then, you have to put the following line at the top of your file:

#!/usr/bin/env python

env 是一个设置环境的小程序，以便执行正确的 python 解释器.

env is a little program that sets up the environment so that the right python interpreter is executed.

您还必须使用命令使您的文件可执行

You also have to make your file executable, with the command

chmod a+x htswap

并将其转储到 /usr/local/bin.这比 /usr/bin 更简洁，因为该目录的内容通常由操作系统管理.

And dump it into /usr/local/bin. This is cleaner than /usr/bin, because the contents of that directory are usually managed by the operating system.
