number of folders in a directory (recursive)

I would like to print the number of folders (recursive, excluding hidden folders) in a given CWD / current directory. What command, or series of commands can I use to ascertain this information?

Method 1

This will find the number of non-hidden directories in the current working directory:

ls -l | grep "^d" | wc -l

EDIT:

To make this recursive, use the -R option to ls -l:

ls -lR | grep "^d" | wc -l

Method 2

In the GNU land:

find . -mindepth 1 -maxdepth 1 -type d -printf . | wc -c

elsewhere

find . -type d ! -name . -printf . -prune | wc -c

In bash:

shopt -s dotglob
count=0
for dir in *; do
  test -d "$dir" || continue
  test . = "$dir" && continue
  test .. = "$dir" && continue
  ((count++))
done
echo $count

Method 3

echo $(($(find -type d | wc -l) - 1)) is one way (subtract 1 from the wc -l to remove the current dir). You can tweak the options to find to find different things.

echo $(($(find -type d -not -path '*/.*' | wc -l) - 1)) – to exclude the hidden dirs

As I mentioned in the comments, the heart of this expression is really find -type d, which finds all directories.

Note this finds all subfolders as well – you can control the depth using the -maxdepth flag.

Method 4

Did you try tree command?

tree -d /path/to/maindir| awk END{print}

Method 5

In zsh:

(){echo $#} *(N/)

Recursively:

(){echo $#} **/*(N/)

Add the D glob qualifiers if you also want to count hidden directories.

POSIX equivalents:

ls -p | grep -c /

(add the -A option to ls for hidden ones)

Recursively:

LC_ALL=C find .//. ! -name . ( -name '.*' -prune -o -type d -print ) |
  grep -c //

Or

LC_ALL=C ls -Rqn . | grep -c '^d'

To include hidden ones:

LC_ALL=C find .//. ! -name . -type d | grep -c //

or:

LC_ALL=C ls -ARqn . | grep -c '^d'

Method 6

find . -type d -not -path '.' -printf 0 | wc -c ;

Recursively find all directories (-type d) within current directory (find .) that is not (.) directory and print 0 for each directory found. Then wc -c counts the number of characters (0) from the previous command output.
