Question

Looking for help creating a script that will replace the last line of an XML file with a tag. I have a few hundred files so I’m looking for something that will process them in a loop. I’ve managed to rename the files sequentially like this:

posts1.xml
posts2.xml
posts3.xml

etc…

to make it easier to loop through. But I have no idea how to write a script to do this. I’m open to using either Linux or Windows (but i would guess that Linux is better for this kind of task).

Answer 1

So if you want to append a line to every file:

sed -i '$a<YOUR_SHINY_NEW_TAG>' *xml

To replace the last line:

sed -i '$s/.*/<YOUR_SHINY_NEW_TAG>/' *xml

But do note, sed is not the ideal tool to modify xml.
