在目录树中递归执行imagemagick合成命令

我有一个很大的目录树，其中有许多子文件夹，每个子文件夹中都有大量图像。我找到了一个脚本，可以将水印应用到目录中的所有图像，就地覆盖原始图像。我正在寻找迭代所有文件夹和子文件夹并为 Linux 服务器上的每个图像运行“compose”命令的最佳方法。这是我找到的原始脚本

#!/bin/bash

# DESCRIPTION:  A script to add a watermark and overwrite all images in a directory.
#
# This script will watermark all of the images in a directory. Warning! This will overwrite the files.
###########################################

# Initialize variables
WM=$HOME/public_html/image/catalog/logo-website/watermark.png  # This is the path to your watermark image
SCALE=100                          # This sets the scale % of your watermark image

# Warning
echo -e "This will overwrite all of the images in this directory."\\n"Are you shure want to continue? {Y/n}"
read REPLY

if
    [ "$REPLY" != "n" ] && [ "$REPLY" != "N" ]
then
    file -i * | grep image | awk -F':' '{ print $1 }' | while read IMAGE
        do
            echo Watermarking $IMAGE
            composite -dissolve 40% -gravity SouthEast -quality 100 \( $WM -resize $SCALE% \) "$IMAGE" "$IMAGE"
        done
else
    echo exiting
    exit 0
fi

exit 0

我应该使用“find . -name *.jpg”的组合还是其他内容？

该脚本已经检查了图像文件的目录，但如果您想调整它以遍历所有目录而不提示您输入每个目录，您不妨重写它。就像是：

#!/bin/bash

WM=$HOME/public_html/image/catalog/logo-website/watermark.png  # This is the path to your watermark image
SCALE=100                          # This sets the scale % of your watermark image
STARTDIR="/home/whatever/images"   # This is the directory to start in

for imagedir in $( find $STARTDIR -type d )
do
  echo "Running in $imagedir ..."
  cd $imagedir
  file -i * | grep image | awk -F':' '{ print $1 }' | while read IMAGE
  do
    echo "Watermarking $IMAGE"
    composite -dissolve 40% -gravity SouthEast -quality 100 \( $WM -resize $SCALE% \) "$IMAGE" "$IMAGE"
  done
done
