Yes, GIDs (Group Identifiers) can be changed in a Linux system. You can change the GID of a group using the groupmod command. Here’s the syntax:
sudo groupmod -g NEW_GID GROUP_NAMEReplace NEW_GID with the desired GID and GROUP_NAME with the name of the group whose GID you want to change.
Keep in mind that changing a GID may affect file permissions and access rights for files owned by that group, so it's important to update any relevant file ownerships accordingly.
