How can I run script for all directories?

Question

Suppose I am at the main directory which contains script.sh and subdirectories, each of subdirectories contain images.
The script.sh is a script for resizing images. I want to apply this script to every subdirectories, so after searching for solution I created another script which is

SAVEIFS=$IFS #Since the subdirectories contain whitespaces in their name
IFS=$(echo -en "\n\b")
for d in ./*; do
  if [ -d "$d" ]; then
    echo "$d" && cp ./script.sh ./$d/script.sh && cd "$d" && exec sh ./script.sh && cd ..
  fi
done
IFS=$SAVEIFS

The problem is this script stops after it's done at the first subdirectory. How can I make it runs for all subdirectories? Or are there better way to make script.sh runs for all subdirectories?

Answer 1

find to the rescue!

CURDIR=`pwd`
IFS=$'\n'
for d in $(find . -type d); 
do 
    cd $CURDIR/"$d"
    $CURDIR/script.sh
done

Even better... strip the "all files in the directory" stuff from your script, and:

IFS=$'\n'
for f in $(find . -type f); 
do 
    ./script.sh "$f"
done
