[rajp152k]

the initial command only works for the BSD variant of sed (MacOS..) A syntax error is raised for the GNU variant
need to remove the extra backup '' after -i

on OpenSuse tumbleweed:
Using the initial command gives

 $ sed -i '' 's/karpor-server.karpor.svc/127.0.0.1/g' $HOME/.kube/karpor-hub-cluster.kubeconfig
sed: can't read s/karpor-server.karpor.svc/127.0.0.1/g: No such file or directory

and after the fix, it works

@rajp152k Yes, you are right. There are differences in the sed command between Mac and Linux. Thank you for your correction!
