특정 디렉토리의 디렉토리 수 계산

특정 디렉토리의 디렉토리 수 계산

---

특정 디렉터리의 폴더 수를 계산하는 방법. 다음 명령을 사용하고 있지만 항상 추가 명령을 제공합니다.

find /directory/ -maxdepth 1 -type d -print| wc -l

예를 들어, 3 개의 폴더가있는 경우이 명령은 4를 제공합니다. 5 개의 폴더가 포함 된 경우 명령은 6을 제공합니다. 그 이유는 무엇입니까?

---

find 디렉토리 자체도 인쇄합니다.

$ find .vim/ -maxdepth 1 -type d
.vim/
.vim/indent
.vim/colors
.vim/doc
.vim/after
.vim/autoload
.vim/compiler
.vim/plugin
.vim/syntax
.vim/ftplugin
.vim/bundle
.vim/ftdetect

대신 디렉토리의 하위 항목을 테스트하고 하위 항목으로 내려 가지 않도록 할 수 있습니다.

$ find .vim/* -maxdepth 0 -type d
.vim/after
.vim/autoload
.vim/bundle
.vim/colors
.vim/compiler
.vim/doc
.vim/ftdetect
.vim/ftplugin
.vim/indent
.vim/plugin
.vim/syntax

$ find .vim/* -maxdepth 0 -type d | wc -l
11
$ find .vim/ -maxdepth 1 -type d | wc -l
12

다음을 사용할 수도 있습니다 ls.

$ ls -l .vim | grep -c ^d
11


$ ls -l .vim
total 52

현재 디렉터리의 디렉터리 수만 가져옵니다.

echo */ | wc

당신은 밖으로 나올 것입니다 1 309 4594

2nd digit아니오를 나타냅니다. 디렉토리의.

또는

tree -L 1 | tail -1

---

find . -mindepth 1 -maxdepth 1 -type d | wc -l

For find -mindepth는 디렉토리의 총 수를 의미합니다.

-maxdepth 디렉토리에 영향을 미치는 총 수를 의미합니다.

-type d 디렉토리를 의미

그리고 for wc -l는 입력의 줄을 세는 것을 의미합니다.

드라이브로 이동하여 실행하는 가장 좋은 방법

ls -lR | grep ^d | wc -l

and to Find all folders in total, including subdirectories?

find /mount/point -type d | wc -l

...or find all folders in the root directory (not including subdirectories)?

find /mount/point -maxdepth 1 -type d | wc -l

Cheers!

Run stat -c %h folder and subtract 2 from the result. This employs only a single subprocess as opposed to the 2 (or even 3) required by most of the other solutions here (typically find plus wc).

Using sh/bash:

cnt=$((`stat -c %h folder` - 2))
echo $cnt   # 'echo' is a sh/bash builtin, not an additional process

Using csh/tcsh:

@ cnt = `stat -c %h folder` - 2
echo $cnt   # 'echo' is a csh/tcsh builtin, not an additional process

Explanation: stat -c %h folder prints the number of hardlinks to folder, and each subfolder under folder contains a ../ entry which is a hardlink back to folder. You must subtract 2 because there are two additional hardlinks in the count:

1. folder's own self-referential ./ entry, and
2. folder's parent's link to folder

---

I think the easiest is

  ls -ld images/* | wc -l

where images is your target directory. The -d flag limits to directories, and the -l flag will perform a per-line listing, compatible with the very familiar wc -l for line count.

---

If you only have directories in the folder and no files this does it:

ls | wc -l

---

A pure bash solution:

shopt -s nullglob
dirs=( /path/to/directory/*/ )
echo "There are ${#dirs[@]} (non-hidden) directories"

If you also want to count the hidden directories:

shopt -s nullglob dotglob
dirs=( /path/to/directory/*/ )
echo "There are ${#dirs[@]} directories (including hidden ones)"

Note that this will also count links to directories. If you don't want that, it's a bit more difficult with this method.

---

Using find:

find /path/to/directory -type d \! -name . -prune -exec printf x \; | wc -c

The trick is to output an x to stdout each time a directory is found, and then use wc to count the number of characters. This will count the number of all directories (including hidden ones), excluding links.

---

The methods presented here are all safe wrt to funny characters that can appear in file names (spaces, newlines, glob characters, etc.).

---

Some useful examples:

count files in current dir

/bin/ls -lA  | egrep -c '^-'

count dirs in current dir

/bin/ls -lA  | egrep -c '^d'

count files and dirs in current dir

/bin/ls -lA  | egrep -c '^-|^d'

count files and dirs in in one subdirectory

/bin/ls -lA  subdir_name/ | egrep -c '^-|^d'

I have noticed a strange thing (at least in my case) :

When I have tried with ls instead /bin/ls the -A parameter do not list implied . and .. NOT WORK as espected. When I use ls that show ./ and ../ So that result wrong count. SOLUTION : /bin/ls instead ls

---

Using zsh:

a=(*(/N)); echo ${#a}

The N is a nullglob, / makes it match directories, # counts. It will neatly cope with spaces in directory names as well as returning 0 if there are no directories.

---

Best way to do it:

ls -la | grep -v total | wc -l

This gives you the perfect count.

---

Count all files and subfolders, windows style:

dir=/YOUR/PATH;f=$(find $dir -type f | wc -l); d=$(find $dir -mindepth 1 -type d | wc -l); echo "$f Files, $d Folders"

---

If you want to use regular expressions, then try:

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