LS with du divided by ls wc-l sub directory average
Hi.

I am trying to write a script that will create a list of directories with their total disk usage (including subdirectories) divided by the number of sub directories.

so i run an ls like this ls -d */images/*/, and that would give me my list. Then i want to get the du of every directory returned in that list, but divided by the number of subdirectories in it. Thereby giving me a subdirectory average of every directory in the output.

Thank you for any help.

shtrashcan

mktrashcan(1)						      General Commands Manual						     mktrashcan(1)

NAME

       mktrashcan, rmtrashcan, shtrashcan - Attaches, detaches, or shows a trashcan directory

SYNOPSIS

       /usr/sbin/mktrashcan trashcan directory...

       /usr/sbin/rmtrashcan directory...

       /usr/sbin/shtrashcan directory...

OPERANDS

       Specifies  the  directory  that	contains  files  that were deleted from attached directories.  Whenever you delete a file in the specified
       directory, the file system automatically moves the file to the trashcan directory.  Specifies the directory that you attach to  a  trashcan
       directory.

DESCRIPTION

       The  trashcan  utilities  (mktrashcan and rmtrashcan) enable you to attach or detach an existing directory, which you specify as a trashcan
       directory, to any number of directories within the same fileset.

       A trashcan directory stores the files that are deleted with the unlink system call. For instance, you can use  the  mktrashcan  utility	to
       attach  a  trashcan  directory called /usr/trashcan to one or more directories; thereafter, when you delete a file from one of the attached
       directories, the file system moves the file to the /usr/trashcan directory.  Note that when more than one directory shares attachment to  a
       trashcan directory, files with the same file name can overwrite each other in the trashcan directory.

       If you mistakenly delete a file, use the mv command to return the file from the /usr/trashcan directory to its original directory.

       When you enter shtrashcan at the system prompt, the system shows the trashcan directory, if one exists, for the directory you specified.

       It is important that trashcan directories have correct access permissions.  If the permissions are too restrictive, then it may be impossi-
       ble to remove files from the directories that are attached to the trashcan directory. In general, all users and groups that expect  to  use
       the  trashcan directory need write permission to the directory. If unexpected "permission denied" errors occur when deleting files that are
       in a directory attached to a trashcan directory, use the chmod command to change the permissions on the trashcan directory.

RESTRICTIONS

       The directory and trashcan directories must be in the same fileset; however, you can attach the trashcan directory to any directory  within
       the fileset.

EXAMPLES

       The  following  example	creates and attaches a trashcan directory, /usr/trashcan, to two directories, /usr/ray and /usr/projects/sql/test,
       which are in the same fileset. The chmod command adds write permission for all users and groups on the new  trashcan  directory.   %  mkdir
       /usr/trashcan  %  chmod	a+w  /usr/trashcan  %  mktrashcan  /usr/trashcan /usr/ray /usr/projects/sql/test To attach the trashcan directory,
       /usr/trashcan, to all subdirectories in the /usr directory, enter: % mktrashcan /usr/trashcan /usr/*

	      New subdirectories that you add beneath the /usr directory are not attached to the trashcan directory until you attach  them.  Also,
	      the mktrashcan utility distinguishes between directories and files, attaching only directories to the trashcan directory.

	      Note  that  an  attached	directory produces an EDUPLICATE_DIRS (-1165) error when /usr/trashcan is itself in the directory path you
	      attach to (as in the previous example).  You can ignore this error message.
