regex - How to remove a line with space using sed?

Question

I want to remove a line which begins with <Field name="LastDate" in a xml file.

The space seems to be creating issues here sed -i /^<Field name="LastDate"/d test.xml. How do I go about this?

Answer 1

スクリプトを引用する必要があります（テキストにはすでに二重引用符が含まれているため、一重引用符）：

$ sed -i '/^<Field name="LastDate"/d' test.xml
