    1.帮同事写的脚本

    #!bin/sh
    for file in ./*
    do
        if test -f $file
        then
            echo $file 是文件
            suffix=.png
            if [[  $file == *$suffix  ]]; then
                 echo "我是png图片"
                #cp $file $storeDir
            fi
            suffix1=.jpg
            if [[  $file == *$suffix1  ]]; then
                 echo "我是jpg图片"
                #cp $file $storeDir
            fi
            #arr=(${arr[*]} $file)
