i love find -execute but sometimes i would like to do more complex operations like running find -execute in all matching folders.
(e.g. run a script on all header files in a subdirectory tree for all base directories that were created after some date).
This can be accomplished with piping the output of one find into the next, like so:
find . -type d -newermt 2021-01-01 -name "src" -print0 \
| xargs0 -IDIR find DIR -type f -name "*.h" -exec sed -e 's|Copyright|©|g' -i {} ";"
However, it would be possible to call one find -execute from another.
Somdething like this:
find . -type d -newermt 2021-01-01 -name "src" -exec \
find {}¹ -type f -name "*.h" -exec \
sed -e 's|Copyright|©|g' -i {}² \
+² \
+¹
The obvious problem is to associate the placeholder ({}) and the expansion specifier (+, resp ;) with the correct find.
In my code above i used the ¹ to indicate association with the 1st find and ² for the 2nd instance.
So my question is: is it possible to call one find from another (multiple layers) or must i use xargs for stacking multiple finds?
