Recursively counting files in a Linux directory

Question

How can I recursively count files in a Linux directory?

I found this:

find DIR_NAME -type f | wc -l

But when I run this it returns the following error.

find: paths must precede expression: |

Answer 1

This should work:

find DIR_NAME -type f | wc -l

Explanation:

• -type f to include only files.
• | (and not |) redirects find command's standard output to wc command's standard input.
• wc (short for word count) counts newlines, words and bytes on its input (docs).
• -l to count just newlines.

Notes:

• Replace DIR_NAME with . to execute the command in the current folder.
• You can also remove the -type f to include directories (and symlinks) in the count.
• It's possible this command will overcount if filenames can contain newline characters.

Explanation of why your example does not work:

In the command you showed, you do not use the "Pipe" (|) to kind-of connect two commands, but the broken bar (|) which the shell does not recognize as a command or something similar. That's why you get that error message.
