如何别名命令行命令？ （苹果电脑） [英] How do I alias a command line command? (Mac)

问题描述

我在一个mac，我写了相当多的python脚本。

每次我需要运行它们时，我必须输入' python script_name.py '。是否有我的方式使它，所以我只需要键入像' p script_name.py '？这将节省一些时间：D

解决方案

我假设你从命令行运行你的脚本？如果是，请在脚本中添加以下行作为第一行：

 ＃！/ usr / bin / python 
  

或

 ＃！/ usr / bin / env python 
  

code> / usr / bin ，然后在Unix /终端提示符处输入以下命令（它使你的脚本可执行）：

  chmod + x script_name.py 
  

那么在您只需要在命令提示符处键入脚本的名称即可运行它。不需要 python 部分命令。也就是

  ./ script_name.py 
  

您也可以使用别名

 
 >  alias p =python
  

c>〜/ .bashrc 文件

I'm on a mac, and I write quite a bit of python scripts.

Every time I need to run them, I have to type 'python script_name.py'. Is there I way to make it so I only have to type like 'p script_name.py'? It would save some time :D

解决方案

I am assuming you are running your script from the command line right? If so, add the following line as the first line in your script:

#!/usr/bin/python

or alternatively

#!/usr/bin/env python

in case the python command is not located in /usr/bin, and then issue the following command once at the Unix/terminal prompt (it makes your script "executable"):

chmod +x script_name.py

from then on you only need to type the name of the script at the command prompt to run it. No python part of the command needed. I.e., simply

./script_name.py 

will run the script.

You can also of course go with the alias, but the above is a cleaner solution in my opinion.

For the alias

alias p="python"

should go into your ~/.bashrc file
