+#       the pidof supports "-x" option. If you want to use it for such a
+#       process:
+#       1) If there is no "pidof -x", replace the "pidof $1" with another
+#          command like(for core-image-minimal):
+#            ps | awk '/'"$1"'/ {print $1}'
+#       Or
+#       2) If there is "pidof -x", replace "pidof" with "pidof -x".
