Find number of files in folder and sub folders?

May be something like

find . -type f | wc -l

would do the trick. Try the command from the parent folder.

find . -name <pattern> -type f finds all files in . and subfolders. The result (a list of files found) is passed (|) to wc -l which counts the number of lines. -name <pattern> only looks for certain files.

Use the tree command. You might need to install the tree package.

It will list all the files and folders under the given folder and list a summary at the end.

To count files (even files without an extension) at the root of the current directory, use:

ls -l | grep ^- | wc -l

To count files (even files without an extension) recursively from the root of the current directory, use:

ls -lR | grep ^- | wc -l

The fastest and easiest way, is to use tree. Its speed is limited by your output terminal, so if you pipe the result to tail -1, you'll get immediate result. You can also control to what directory level you like the results, using the -L option. For colorized output, use -C. For example:

$ tree share/some/directory/ | tail -1
558 directories, 853 files

$ tree -L 2 share/some/directory/ | tail -1
120 directories, 3 files
