[SOLVED] How can I find the total disk space used by all files with the same extension (*.dat)

I'm running SLES10 SP2 and using the XFS filesystem

Thanks in advance

AS long as they are all in one dir you can use du

Code:

 du -hsc ./*.pet
4.0K    ./10.pet
4.0K    ./11.pet
4.0K    ./12.pet
4.0K    ./13.pet
4.0K    ./14.pet
4.0K    ./15.pet
4.0K    ./16.pet
4.0K    ./17.pet
4.0K    ./18.pet
4.0K    ./19.pet
4.0K    ./1.pet
4.0K    ./20.pet
4.0K    ./2.pet
4.0K    ./3.pet
4.0K    ./4.pet
4.0K    ./5.pet
4.0K    ./6.pet
4.0K    ./7.pet
4.0K    ./8.pet
4.0K    ./9.pet
80K     total

Unfortunately the files are not all in the same dir.

find / -iname '*.dat' -type f -print0 | xargs -0 du -hsc

Change / in the find to something more appropriate, / tells it to start at the root of the drive so that may not be what you want and will take longer. The -type f part tells it to only look for files, not directories. The -print0 and xargs -0 makes things cleaner when passing to du (disk usage).

Cheers JLM - that looks exactly what I'm after.

then check du's man page. there's an option for recursive listing.
