Faster iteration over thousands of files
I'm trying to do something on ~200,000 files in a single folder.
When I do this:
for i in *; do /bin/echo -n "."; done
One dot is printed every few seconds. The same operation on a folder with a hundred files works blazingly fast.
Why is this so? How to accelerate the process for folders with thousands of files?
Try this with GNU find:
find . -maxdepth 1 -type f -printf "."
