为在 Ubuntu 中执行 python 脚本创建终端名称

Question

I have a python file in: '/home/username/scripts/pyscript' and I want set a word for execute directly this script.

I want do this "python3 /home/username/scripts/pyscript/main.py arg1 arg2" but looks like this "myscript arg1 arg2"

Is this posible? Thank you anyway.

Answer 1

It is possibile in a number of ways. Links are for Bash , supposedly your shell but the ideas always apply.

First option: make a shell alias

alias myscript='python3 /home/username/scripts/pyscript/main.py'

Be sure to add the alias to your.profile to make it survive logout.

Second option: define a wrapper script . Create a file with the following content, named after your desired command (eg myscript):

#!/bin/bash
python3 /home/username/scripts/pyscript/main.py "$@"

save it and make it executable, then call it:

chmod +x myscript
./myscript arg1 arg2

Be sure to copy the script in a folder in your PATH (check where with echo $PATH) to be able to call it from any folder.

You can also use pyinstaller to create a single file executable:

Step 1: Install pyinstaller

_{[Note: best practice is to do this in a virutalenv ]}

$ pip install pyinstaller

Step 2: Run pyinstaller against your script

$ pyinstaller --console --onefile /home/username/scripts/pyscript

$ pyinstaller pyscript.spec  # use this after the first run

Step 3: Test the generated executable

$ cd /home/username/scripts/dist  # generated by pyinstaller
$ pyscript arg1 arg2

Step 4: Leverage the $PATH variable

$ cp /home/username/scripts/dist/pyscript /usr/bin

You should now be able to run the executable from anywhere.

It should be noted that the executable that is generated is OS specific. For example, if you generate it on an Ubuntu machine, it will only run on Ubuntu (Debian based). The same holds true for Windows and other Linux distros.

Finally I solver with the help of @pierpaciugo I add a alias at the end of the.bashrc for make it persistent:

alias create='bash /home/username/Programming/Python/GithubAPI/script.sh'

I couldn't use only alias because I have my python dependencies on a virtual environment so if I try this i could not add params to my python script.

For that I create this bash script:

#!/bin/bash

source /home/username/Programming/Python/GithubAPI/venv/bin/activate && python3 /home/username/Programming/Python/GithubAPI/main.py $@ && deactivate

Now I can write "create param1 param2" and it works. I am using all global paths but could be a good idea add the script in a folder in my PATH.
