Linux CLI - Environment and Configuration

You want to ensure your shell environment always uses Python 3.12 from $HOME/python3.12/bin before any system Python. How should you modify your .bashrc to achieve this?

Aexport PATH="$HOME/python3.12/bin:$PATH"

Bexport PATH="$PATH:$HOME/python3.12/bin"

Calias python="$HOME/python3.12/bin/python3"

Dset PATH="$HOME/python3.12/bin:$PATH"

Step-by-Step Solution

Solution:

Step 1: Understand PATH priority
Paths at the start of PATH variable have higher priority when searching commands.
Step 2: Prepend custom Python path
Prepending $HOME/python3.12/bin ensures this Python is found first.
Step 3: Check syntax correctness
Only export PATH="$HOME/python3.12/bin:$PATH" correctly prepends and exports PATH.
Final Answer:
export PATH="$HOME/python3.12/bin:$PATH" -> Option A
Quick Check:
Prepend custom path with export PATH [OK]

Quick Trick: Prepend custom bin to PATH with export [OK]

Common Mistakes:

Appending path instead of prepending
Using alias instead of PATH modification
Using 'set' which is invalid in bash
