# Below is a sample snippet, which you can put into your shell's init
# file, e.g. into '~/.bashrc'.
# It defines a custom shell function called 'klog', which overshadows
# the 'klog' binary from your '$PATH'. That way, you can intercept any
# input arguments, add your own custom subcommands, or override the
# output to your liking.
# Everything else will be passed through as is.

klog() {
  # Intercept the 'total' subcommand to make it only print the first line
  # of the output.
  if [[ "$1" == "total" ]]; then
   command klog total "${@:2}" | head -n 1

  # Add a custom subcommand to klog ('klog new'), that would create a new
  # record with specific parameters.
  elif [[ "$1" == "new" ]]; then
    command klog create \
      --should='8h' \
      --summary='New day at work' \
      "${@:2}"

  # Pass through all other invocations as is.
  else
    command klog "$@"
  fi
