counting number of directories in a specific directory

Question

How to count the number of folders in a specific directory  I am using the following command  but it always provides an extra one    find  directory  -maxdepth 1 -type d -print  wc -l   For example  if I have 3 folders  this command provides 4  If it contains 5 folders  the command provides 6  Why is that

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

find is also printing the directory itself     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   You can instead test the directory s children and do not descend into them at all     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   You can also use ls     ls -l  vim   grep -c  d 11     ls -l  vim total 52 drwxrwxr-x  3 anossovp anossovp 4096 Aug 29  2012 after drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 autoload drwxrwxr-x 13 anossovp anossovp 4096 Aug 29  2012 bundle drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 colors drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 compiler drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 doc -rw-rw-r--  1 anossovp anossovp   48 Aug 29  2012 filetype vim drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 ftdetect drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 ftplugin drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 indent drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 plugin -rw-rw-r--  1 anossovp anossovp 2505 Aug 29  2012 README rst drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 syntax    ls -l  vim   grep  d drwxrwxr-x  3 anossovp anossovp 4096 Aug 29  2012 after drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 autoload drwxrwxr-x 13 anossovp anossovp 4096 Aug 29  2012 bundle drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 colors drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 compiler drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 doc drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 ftdetect drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 ftplugin drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 indent drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 plugin drwxrwxr-x  2 anossovp anossovp 4096 Aug 29  2012 syntax

Best way to navigate to your drive and simply execute  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

If you only have directories in the folder and no files this does it   ls   wc -l

Get a count of only the directories in the current directory  echo      wc  you will get out put like 1     309    4594   2nd digit represents no  of directories   or   tree -L 1   tail -1

find   -mindepth 1 -maxdepth 1 -type d   wc -l   For find -mindepth means total number recusive in directories  -maxdepth means total number recusive in directories  -type d means directory  And for wc -l means count the lines of the input

Best way to do it   ls -la   grep -v total   wc -l   This gives you the perfect count

User · Answer

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

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 nbsp  nbsp     echo  is a sh bash builtin  not an additional process   Using csh tcsh        cnt    stat -c  h folder  - 2   echo  cnt nbsp  nbsp     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    folder s own self-referential    entry  and folder s parent s link to folder

The best answer to what you want is  echo  find   -maxdepth 1 -type d   wc -l -1   bc   this subtracts one to remove the unwanted     directory that find lists  as patel deven mentioned above    If you want to count subfolders recursively  then just leave off the maxdepth option  so  echo  find   -type d   wc -l -1   bc   PS If you find command substitution ugly  subtracting one can be done as a pure stream using sed and bc   Subtracting one from count   find   -maxdepth 1 -type d   wc -l   sed  s   -1 n     bc   or  adding count to minus one   find   -maxdepth 1 -type d   wc -l   sed  s   -1      bc

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
