Linux Foundation Certified System Administrator (LFCS) — Question 100

Which variable defines the directories in which a Bash shell searches for executable commands?

Answer options

• A. BASHEXEC
• B. BASHRC
• C. PATH
• D. EXECPATH
• E. PATHRC

Correct answer: C

Explanation

The correct answer is PATH, as it is the environment variable that holds a list of directories for the shell to search for executable files. The other options, such as BASHEXEC, BASHRC, EXECPATH, and PATHRC, do not serve this purpose and are either related to different functionalities or do not exist as standard Bash variables.
