bash 脚本中的空行给出“未找到”

Question

我有一个无法正常运行的脚本。我问了一个关于同一个脚本的问题并让它工作不久以前。但现在同一个脚本给出了其他错误，我不知道为什么。

我收到这些错误消息：

: not foundntstore.sh: 4: restore_eventstore.sh:
: not foundntstore.sh: 6: restore_eventstore.sh:
restore_eventstore.sh: 46: restore_eventstore.sh: Syntax error: end of file unexpected (expecting "then")

当我跑步时

sh restore_eventstore.sh 2023-01-04-03-00.tar.gz

剧本：
