Linux CLI - Environment and Configuration

You want to set a variable CONFIG_PATH to /etc/config and ensure it is available to all scripts run from your current shell session and its children. Which sequence of commands achieves this correctly?

ACONFIG_PATH=/etc/config\nexport CONFIG_PATH

Bexport CONFIG_PATH=/etc/config

Cexport CONFIG_PATH\nCONFIG_PATH=/etc/config

DCONFIG_PATH=/etc/config

Step-by-Step Solution

Solution:

Step 1: Assign variable before export
Assigning CONFIG_PATH=/etc/config sets the value in the current shell.
Step 2: Export variable after assignment
Running export CONFIG_PATH marks it for child processes with the assigned value.
Step 3: Check other options
export CONFIG_PATH=/etc/config works but is less clear; export CONFIG_PATH\nCONFIG_PATH=/etc/config exports before assignment (wrong); CONFIG_PATH=/etc/config does not export.
Final Answer:
CONFIG_PATH=/etc/config export CONFIG_PATH -> Option A
Quick Check:
Assign then export to share variable [OK]

Quick Trick: Assign first, then export to share variable [OK]

Common Mistakes:

Exporting before assigning value
Not exporting variable at all
Assuming single export with assignment is always best
