我在木星笔记本中使用了以下代码。
%%bash -s "$store_path" "$store_file"
! echo a = $1, b = $2
! cat $1 | awk '{ print length, $0 }' | sort -n -s | cut -d ' ' -f 2- | awk '!a[$0]++' > $2
这以前用来完美地工作，并且经过了很长的差距，我试图使用此代码。它显示了下面的问题，我不知道。

我试图通过使用一行作为import subprocess来操纵，但它不会成功。我尝试使用的另一件事是使用%代替%%，但这也行不通。需要帮助。
一旦%%在顶部，则在连续的行中不需要!。另外，从关于旧代码的记忆中，也应避免使用#在魔术单元内插入顶部的注释，因为它也会产生一些错误。
