我试图打印以下代码 20 次而不必复制 20 次，因为它是一个随机数生成器，并且我希望每张表都不同，所以我遇到了麻烦。

有人建议我使用 Zhs 和以下代码；
for i in {1..20}
do
xelatex practiseworksheet.tex
mv practiseworksheet.pdf worksheetcopy$i.pdf
done
gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=exercise20.pdf worksheetcopy*.pdf
但我无法让它工作，有人有什么想法吗？
很抱歉，这可能超出了我的能力范围，但当我尝试所有建议时，我只收到这个错误：
