What command is used to count the number of files in the current directory by using pipes ?
Correct answer: C. ls | wc - l
- A. ls | ws - c
- B. ls | wc - w
- C. ls | wc - l
- D. ls | wc
Explanation
`ls` produces one directory entry per line in its normal output, and `wc -l` counts those lines. This counts displayed entries rather than strictly all files, since hidden entries are omitted and subdirectories are counted as entries.
