Context

After exporting a script to ~/bin/script_name and running it successfully from the CLI at an arbitrary place with: script_name, I have updated the content of the script. However, this update is not reflected in the behaviour.

Old content:

#!/bin/bash

echo "Old world"

New content:

#!/bin/bash

echo "Hello world"

I saved the file, and reopened it, and it shows the new content.

Expected output:

Hello world

Actual output:

Old world

Question

How can I ensure the renewed content from the ~/bin/script_name is used when I call it from an arbitrary location using: script_name?

Attempts

First I tried closing and re-opening the terminal. Then I tried rebooting, both show the same, unexpected (to me) behaviour.

Additional information

Ubuntu 22.10, and the $PATH content is:

/home/name/miniconda/envs/snncompare/bin:/home/name/miniconda/condabin:/home/name/.local/bin:/home/name/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin
