unexpected pipeline result with find -exec

Hi All,

I probably miss something fundamental here.
I want to rename a bunch of files in subdirectories (that might contain white spaces) with names that are related.

I thought following could do the job:

Code:

find . -name *.sh -exec mv {} $(echo {} | sed -e 's/0/1/g') \;

Now to be able to see the output I generate an echo of the substitutes:

Code:

find . -name *.sh -exec echo {} $(echo {} | sed -e 's/0/1/g') \;

Interestingly echo {} equals echo {} | sed -e 's/0/1/g'.
It looks like the substitution of {} is somehow not done in the order I expected.

If I try the pipelining directly (without ${..}) it generates the right substitution (but for my purpose not usable):

Code:

find . -name *.sh -exec echo {} $(echo "2001" | sed -e 's/0/1/g') \;

Thank you very much for any idea pointing out my mistake,
best,
blued
