我有一个文件，其中只包含一行，但它真的真的很长。我想从该行的特定部分，并取代其他东西。
以下是示例测试：

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.

我想象-〉以**"示例文本"开头以"实际案例"结尾**
预期结果：* "示例文本在我的实际情况中应该是很长的文本"*
替换：空的
你能帮帮我吗？

查找this，假设您使用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"}"
