Linux匹配起止并替换

Question

我有一个只包含一行的文件，但它真的很长。 我想从线路中获取特定部分并替换为其他部分。

下面是一个示例测试：

This is an exemple text should be very long long text in my real case i am trying to find something like start/end with to replace to something else.

我在想象 -> 从“示例文本”开始，以“真实案例”结束

预期结果： “在我的真实案例中，示例文本应该是非常长的文本”

替换：空

请你帮助我好吗？

看看这个，假设你使用 bash：

myString="This is an exemple text should be very long long text in my real case i am trying to find something like start/end with to replace to something else."
echo "${myString/"This is an exemple text should be very long long text in my real case i am trying to find something like start/end with to replace to something else."/"exemple text should be very long long text in my real case"}"
