After Modified Files?

I got question, when I modified after, check by ./validate.php, WARN message show me:

[librenms@librenms ~]$ sudo sed -i ‘s/90B040/00CC00/g’ /opt/librenms/includes/html/graphs/
[librenms@librenms ~]$ sudo sed -i ‘s/8080C0/0000FF/g’ /opt/librenms/includes/html/graphs/
[librenms@librenms ~]$
[librenms@librenms ~]$ ./validate.php

[WARN] Your local git contains modified files, this could prevent automatic updates.
You can fix this with ./scripts/github-remove
Modified Files:
[librenms@librenms ~]$

But I don’t want running command: ./scripts/github-remove
How to eliminate this message?

You can revert an individual file by doing , as librenms user:
git checkout <path to the file>
