Linux Foundation Certified System Administrator (LFCS) — Question 103

Which of the following commands can be used to search for the executable file foo when it has been placed in a directory not included in $PATH?

Answer options

• A. apropos
• B. which
• C. find
• D. query
• E. whereis

Correct answer: C

Explanation

The correct answer is C (find) because it allows you to search through directories for files matching specific criteria. The other options, like which and whereis, are used to locate executables in standard directories listed in $PATH, and apropos provides descriptions of commands, while query is not a standard command for this purpose.
