Question

我有这个cgi脚本：

echo "Content-type: text/html"
echo ""
echo "<html><head><title>Demo</title></head><body>"
echo "env: $(env)"
echo "Current directory is $(pwd) <br>"
echo "Shell Script name is $0"
echo "</body></html>"

浏览器中的输出字面意思是：

有没有一种方法可以将每个环境变量对回显到新行？

Answer 1

不需要表，只需使用<br>，就像这样：

env | sort | while read line; do echo "$line <br>"; done

将环境回显到简单表
