使用命令行打开python脚本

Question

I created python script ( "hello.py" for example). But I would like to open script from any directory using:

darker0n@MacBook ~>hello

Answer 1

Create a custom command that'll invoke your Python script.

Let's say your hello.py is in the path /home/python/hello.py

Create a custom script called hello containing:

python /home/python/hello.py .

You can put it a hidden directory so that it remains hidden.

Say you've added it to the following file: /home/python/.custom/hello . Now add the following line to your .bashrc (or equivalent) file:

export PATH=$PATH":/home/python/.custom

Next time you open a terminal and type hello , you get the script to run. To get it immediately in any already open terminal sessions, simply run source ~/.bashrc

Answer 2

Use a shell interpreter line, (shebang line). For example, in a file called hello.

#!/usr/bin/env python
python code here
...

then

chmod +x hello

and put the hello script somewhere in your PATH.

Oh and don't type

~>hello

that is a syntax error, and the > will redirect output to a file hello, overwrite it with nothing, as the "~" is not really a command, but a special shell $HOME directory spec. Unless the ~> is part of your prompt, then ignore this warning.

Answer 3

You can create a symbolic link in your /usr/local/bin folder (or any folder in your PATH env variable) with the command:

ln -s  /path/to/hello.py /usr/local/bin/hello

This will allow to keep your script in your preferred path and having the possibility to modify it anytime.
