(solved)How to use jpegoptim recursively in subfolders.

Question

Hello ,
I want to optimize some images without changing names with many subfolders loaded.
I am not good at shell script. I found this for jpegtran but package does not work.
How can I modifiye it for jpegoptim?
#! /bin/sh
# Usage 1:
# optimize-images.sh /images/dir
# Usage 2:
# cd /images/dir
# optimize-images.sh
EXTENSIONS="jpe?g"
if [ -z "$1" ]; then
DIR="`pwd`"
else
DIR="$1"
fi
# Optimize JPEG images
find "$DIR" -regextype posix-egrep -regex ".*\.($EXTENSIONS)\$" -type f | xargs -I{} jpegtran -optimize -progressive -outfile "{}.optimized" "{}"
# Rename xxx.jpg.optimized -> xxx.jpg
find "$DIR" -name '*.optimized' -print0 | while read -d $'\0' file; do
chown $(stat -c "%U:%G" "${file%.optimized}") "$file"
chmod $(stat -c "%a" "${file%.optimized}") "$file"
mv -f "$file" "${file%.optimized}";
done
ps1: also found this while google in but I dont know where to write it :
optimize() {
jpegoptim *.jpg --strip-all
for i in *
do
if test -d $i
then
cd $i
echo $i
optimize
cd ..
fi
done
echo
optimize

pkgfile shows what's in the sync databases (in the repos), not what is in the local databases (what do you have on your computer).

works with jpegoptim. I think the same will occur with jpegtran. I had a $PATH value for ruby , it was ruining my bashrc. I commented it and works now.
How exactly were you trying to use the script for jpegtran? Did you put it in your ~/.bashrc? You don't have to put your script location in your $PATH to run it, you just need to use the full path then.
