Linux CLI - Environment and Configuration

You want to add /custom/bin to your PATH only for your current terminal session without affecting others. Which command should you use?

Aset PATH=/custom/bin:$PATH

Bexport PATH=/custom/bin:$PATH

Csudo export PATH=/custom/bin:$PATH

Decho '/custom/bin' >> ~/.bashrc

Step-by-Step Solution

Solution:

Step 1: Identify session-only PATH change
Using export PATH=/custom/bin:$PATH changes PATH only in current shell session.
Step 2: Evaluate other options
echo '/custom/bin' >> ~/.bashrc appends to .bashrc, affecting future sessions, not current only. sudo export PATH=/custom/bin:$PATH uses sudo unnecessarily and is invalid syntax. set PATH=/custom/bin:$PATH uses wrong command 'set'.
Final Answer:
export PATH=/custom/bin:$PATH -> Option B
Quick Check:
Use export for session-only PATH change [OK]

Quick Trick: Use export to change PATH only in current session [OK]
