Remove everything after `xml_` in all filenames in directory

I want to remove the timestamp from all the files in a directory

Let’s say I have below files

ABC.xml_202401012300
XYZ.xml_202401022300 

I want to remove all after xml_

This means I’m expecting

ABC.xml
XYZ.xml

I tried bellow code but did not work :

rename 's/xml_.*$/.xml/' *

>Solution :

In general you can use mv to rename a file in Linux shell. If you want to rename mutliple xml files, you can do it the following way:

for f in *.xml_*; do mv "$f" "${f%_*}"; done

Here %_* is a pattern remover which says remove everything after the underscore symbol.
