Getting the disk usage for certain files per directory.

[cergun]

Hi,

I am trying to get the total file size for certain files per directory.

I am using

find `pwd` /DirectoryPath -name '*.dta' -exec ls -l {} \; | awk '{ print $NF ": " $5 }' > /users/cergun/My\ Documents/dtafiles.txt

but this lists all the files in the directories.

I need the total per directory for all dta files.

Any suggestions?

Try this:

du -ch *.dta

If you have many files and you just want to see the last line with the summary, use the following:

du -ch *.dta | grep total

But this only shows the directory you are in or have selected (i. e.)

du -ch /DirectoryPath/*.dta | grep total > /users/cergun/My\ Documents/dtafiles.txt

for your example.

du in general can list an summarize sub directories but then, you can not select a filename.

If beside the .dta files there are only files ending with .bak, you can do this using the exclude option.

 du -sh --exclude *.bak

or

 du -sh --exclude /DirectoryPath/*.bak | grep total  > /users/cergun/My\ Documents/dtafiles.txt

for your example.

If you have multiple filetypes you can put those in a file and call it duexlude.lst and then call it as follows.

 du -sh -X duexclude.lst /DirectoryPath/*.bak | grep total  > /users/cergun/My\ Documents/dtafiles.txt

hope this helps. Try man du for more options.
