Display a Count of Files in the Current Directory
If you want to get a count of how many files are in a specific directory, you can do so easily with a simple command.
This command uses the -1 (that's a one) parameter of ls to display each file on a new line, and then the -l (lowercase L) parameter of the wordcount (wc) utility.
ls -1 | wc -l
