How to apply du (f.x.) to all sub directories except for some of them

disk-usage

./a
 |-/bx1
 |-/by2
 |-/bz3
 |-/bx4
 |-/by5

Now I want to apply du to all sub-folders except for /by2 and /bx4.

I can make it happen for one folder:

du --max-depth=1 --exclude=./by2

but not for two.

I found to related questions:

In (1) regular expressions are applied which won't work in my case – at least not comfortably. In (2) the exclusion refers to a full sub-directory. Essentially my question is:

Can I feed --exclude a list of files/directories and if yes, how?

Best Answer

du --max-depth=1 --exclude=./by2 --exclude=./bx4 ./a

Disk Usage – How to Count All Files Recursively Through Directories

find . -maxdepth 1 -type d | while read -r dir
do printf "%s:\t" "$dir"; find "$dir" -type f | wc -l; done

Thanks to Gilles and xenoterracide for safety/compatibility fixes.

The first part: find . -maxdepth 1 -type d will return a list of all directories in the current working directory. (Warning: -maxdepth is a GNU extension and might not be present in non-GNU versions of find.) This is piped to...

The second part: while read -r dir; do (shown above as while read -r dir(newline)do) begins a while loop – as long as the pipe coming into the while is open (which is until the entire list of directories is sent), the read command will place the next line into the variable dir. Then it continues...

The third part: printf "%s:\t" "$dir" will print the string in $dir (which is holding one of the directory names) followed by a colon and a tab (but not a newline).

The fourth part: find "$dir" -type f makes a list of all the files inside the directory whose name is held in $dir. This list is sent to...

The fifth part: wc -l counts the number of lines that are sent into its standard input.

The final part: done simply ends the while loop.

So we get a list of all the directories in the current directory. For each of those directories, we generate a list of all the files in it so that we can count them all using wc -l. The result will look like:

./dir1: 234
./dir2: 11
./dir3: 2199

Shell – Getting size of directories and exclude some folders

Something like this should do it.

$ du -s application[12]

Example

$ ls -l
total 16
drwxrwxr-x 2 saml saml 4096 Nov 28 01:51 application1
drwxrwxr-x 2 saml saml 4096 Nov 28 01:51 application1_edit
drwxrwxr-x 2 saml saml 4096 Nov 28 01:51 application2
drwxrwxr-x 2 saml saml 4096 Nov 28 01:51 application2_edit

Disk usage:

$ du -s application[12]
4   application1
4   application2
