The number of files in the linux directory

There is no direct command in linux to display the number of files in a directory. You can combine two commands through a pipeline to
view the number of all files in a directory. The command is as follows:
ls |wc -l
1. ls is to view all files in a folder Command
2. wc -l is a command to count the number of lines in a file.
3. The above two commands are superimposed, which is equivalent to counting the total number of files in the folder.
