Make your Python script executable from anywhere in Linux

Follow the instructions to make your python script executable from anywhere in Linux system.

Python makes life so easy to write scripts for our desired outputs. Sometimes, we simply write a Python utility program that we want access from anywhere in the whole system. I will go through the series of steps you can follow to make your Python script executable in Linux (or Unix-like) system.

Define the shebang as the python path

We use shebang (or #!) a lot in computing. When a text file with a shebang is used as if it is an executable in a Linux, the program loader mechanism parses the rest of the file’s initial line as an interpreter directive.

We can make use of this concept. I added the path to the anaconda python (for the specific environment) as the first line of my Python script. The python script will look like below:

#!/home/utpal/miniconda3/envs/stadenv/bin/python
import os, glob
### rest of the script

In addition to this, you will have to make the script executable in linux:

chmod +x myscript.py

Create environment in the home directory

In your terminal, type:

cd ~/ #navigate to the home directory
mkdir bin

Now, open the ~/.bashrc file in your favourite editor.

code ~/.bashrc #to open the bashrc file using vscode

Now, add your bin directory to the system PATH.

export PATH="$HOME/bin:$PATH"

Bring the python script in the system path

Finally, all we have to do is to copy the script to the system path (the bin directory).

cp myscript.py ~/bin/

Now, restart your terminal and you should have access to the Python script from any location on your system.
