Hi,

I tried using du through find - exec and didn't get the results I expected:

Code:
# find /dir/ -iname '*searchterm*' -exec du -ch \; | grep total
1.1G    total
# du -ch /dir/subdir/searchterm_directory_match
20G     /dir/subdir/searchterm_directory_match
20G     total


What did I do wrong..? :)

You need to pass {} as placeholder for the filename:
Code:
# find ... -exec du -ch {} \;

flangemonkey ....

You need to pass the result of the find to exec ... so, for example:

Code:
% find /path -type d -exec du -ch '{}' \;

In the above your searching for a 'file' and then expecting the 'total' for the directory, so of course the results of the two commands are different. So, what is it you want, the directory size or the filesize? I ask as you can pass a pattern to du:

Code:
du -ch ~/path/*.txt

... but this doesn't provide the size of the directory, so, some idea of what specificly your after.

best ... khay
