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

for (( i=0; i<$image_type_remove_length; i++))
{

echo "Remove No.$i image: $image_remove";
rm -rf $image_remove
}
echo "Files in petalinux image directory: $1 after deleting."
ls -l -h $1
echo -e "Complete script: $0"
peta-del-build-temp-inner.sh 内容如下：
