Question

Which command chain will count the number of regular files named foo.txt located within /home?

A ls -lR /home | grep foo.txt | wc -l
B find /home -type f -name foo.txt | wc -l
C find /home -name foo.txt -count
D find /home -name foo.txt | wc -l
E grep -R foo.txt /home | wc -l

Explanation

The find utility's -type f flag restricts results to regular files, and -name foo.txt matches files with that exact name. Piping the output to wc -l counts the resulting lines, giving an accurate count of regular files named foo.txt. This is documented behavior of the GNU findutils find command, where -type f is the standard way to filter for regular files as opposed to directories, symlinks, or other file types.
