Linux Essentials (010-160) — Question 8

Which of the following commands adds the directory /new/dir/ to the PATH environment variable?

Answer options

• A. $PATH=/new/dir: $PATH
• B. PATH=/new/dir: PATH
• C. export PATH=/new/dir: PATH
• D. export $PATH=/new/dir: $PATH
• E. export PATH=/new/dir: $PATH

Correct answer: E

Explanation

The correct answer is E because it properly uses the export command to set the PATH variable to include /new/dir/ at the start, ensuring it is available to child processes. Option A is incorrect because it does not use the export command, while options B and C do not correctly format the variable assignment. Option D is incorrect as it attempts to export $PATH instead of PATH.
