Thanks for your contribution, but -c cannot be used instead of -config because -c is already taken in the subcommand add.

kubecm add [flags]
Note: If -c is set and more than one context is added to the kubeconfig file, the following will occur:
- If --context-name is set, the context will be generated as <context-name-0>, <context-name-1> ...
- If --context-name is not set, it will be generated as <file-name-{hash}> where {hash} is the MD5 hash of the file name.

# Merge test.yaml with $HOME/.kube/config
kubecm add -f test.yaml 
# Merge test.yaml with $HOME/.kube/config and rename context name
kubecm add -cf test.yaml --context-name test
# Add kubeconfig from stdin
cat /etc/kubernetes/admin.conf |  kubecm add -f -
      --context-name string   override context name when add kubeconfig context
  -c, --cover                 Overwrite local kubeconfig files
  -f, --file string           Path to merge kubeconfig files
  -h, --help                  help for add

Oh right. I will add it only for --ui-size
