Hi, How can I can insert the contents of a file into another file right before a specific line using sed. example I have file1.xml that has the following: <field tagRef="376"> </field> <field tagRef="377"> </field> <field tagRef="58"> </field> <group ref="StandardMessageTrailer" required="true"/> </fieldList> and file2.xml has the following: <field tagRef="9647"> <description>Offset</description> </field> <field tagRef="9648"> <description>Offset Units/Direction</description> </field> <field tagRef="9646"> <description>Anchor Price</description> </field> how can i insert the contents of file2 into file1 just before so it will look like this: <field tagRef="376"> </field> <field tagRef="377"> </field> <field tagRef="58"> </field> <field tagRef="9647"> <description>Offset</description> </field> <field tagRef="9648"> <description>Offset Units/Direction</description> </field> <field tagRef="9646"> <description>Anchor Price</description> </field> <group ref="StandardMessageTrailer" required="true"/> </fieldList> I know how to insert after that line using sed 'group ref="StandardMessageTrailer"/r file2.xml' file1.xml newfile.xml but I want to insert it before. appreciate the help
