自动删除当前目录及其子目录下的所有PetaLinux工程的build目录下的临时文件，释放2TB硬盘空间

服务器报告硬盘没有空间。

执行脚本peta-del-build-temp.sh，自动删除当前目录及其子目录下的所有PetaLinux工程的build目录下的临时文件，最后从历年遗留的100多个工程中释放了2TB硬盘空间。

peta-del-images-unused.sh 内容如下：

#!/bin/bash
# hankf@amd.com

echo -e "\nBegin to run script: $0"

# $1: target-petalinux-image-directory
if [ "$1" = "" ]; then
    echo "Invalid target directory."
    echo "Usage: $0 target-petalinux-image-directory."
fi

echo "Check petalinux image directory: $1"
ls -l -h $1

if [ ! -f  $1/u-boot.elf ]; then 
    echo "Not PetaLinux project image directory, No u-boot.elf."
    echo "Exit."
    exit 1
fi 

if [ ! -f  $1/system.dtb ]; then 
    echo "Not PetaLinux project image directory, No system.dtb."
    echo "Exit."
    exit 1
fi
