The -toption expects a single separator character, but you give it two. A way to do what you want would be to consider that the separator is only a single ;, and thus the third column would become the fifth one:
该-t选项需要一个分隔符，但您给它两个。做你想做的一种方法是考虑分隔符只是一个;，因此第三列将成为第五列：
sort -t ';' -k 5 -r -n -o output.txt input.txt

Since the -t option expects a single separator character, a good way to handle this would be to use a replace tool to temporarily replace the separator(s) with a new one, do the sort, and then restore the original separator(s) as needed for further processing. I have a file that uses "," as separator which I can temporarily replace with a | (pipe), do my sort, and then restore "," as separator.
由于 -t 选项需要单个分隔符，因此处理此问题的一个好方法是使用替换工具将分隔符临时替换为新的分隔符，进行排序，然后恢复原始分隔符根据进一步处理的需要。我有一个使用“,”作为分隔符的文件，我可以暂时用 | 替换它。（管道），做我的排序，然后恢复“，”作为分隔符。
