shell脚本之 给PNG图片添加后缀@3x

1，给png图片加上后缀@3x

#!/bin/sh

#root_src=$(dirname $(PWD))
#echo ${root_src}

image_path=${root_src}/imagesecho ${image_path}
# find ${image_path} -name *.png  -exec echo {} \;
# find ${image_path}  -name *.png -o  -name *.jpg -print
# find ${image_path} -path '*/Assets.xcassets*' -prune -o  -name *.png
# find ${image_path} -path '*/Assets.xcassets*' -prune -o  \( -name *.png  -o  -name *.jpg \) -print

pngfiles=`find ${image_path} -name *.png `
suffix2x='@3x.png'
suffix3x='@2x.png'
for file in $pngfiles
do
    if [[ ${file} =~ ${suffix2x} || ${file} =~ ${suffix3x}  ]]
      then
        echo "${file}不变"

    else
        echo "${file}需要添加@3x"
        mv ${file} "${file%.png}@3x.png"
    fi

done

2,进化版：查找当前目录下除Assets.xcssets，给所有无后缀的jpg或者png添加后缀为@3x。

根据需求不同，可以酌情更改Find命令等

#!/bin/sh

image_path=`pwd`
echo ${image_path}
# find ${image_path} -name *.png  -exec echo {} \;
# find ${image_path}  -name *.png -o  -name *.jpg -print #寻找png或者jpg
# find ${image_path} -path '*/Assets.xcassets*' -prune -o  -name *.png  #查找目录下除Assets.xcassets以外的目录
#查找除去Assets.xcassets以外的${image_path}目录下，结尾为png或者jpg的图片
# find ${image_path} -path '*/Assets.xcassets*' -prune -o  \( -name *.png  -o  -name *.jpg \) -print

pngfiles=`find ${image_path} -path '*/Assets.xcassets*' -prune -o  \( -name *.png  -o  -name *.jpg \)  `
suffix2x='@3x.png'
suffix3x='@2x.png'
for file in $pngfiles
do
    if [[ ${file} =~ ${suffix2x} || ${file} =~ ${suffix3x}  ]]
      then
        echo "${file}不变"

    else
        if [[ ${file} =~ '.png' ]]; then
             echo "PNG图片${file}需要添加@3x"
                mv ${file} "${file%.png}@3x.png"
        fi
        if [[ ${file} =~ '.jpg' ]]; then
            echo "jpg图片${file}需要添加@3x"
                mv ${file} "${file%.jpg}@3x.jpg"
        fi

    fi

done
