the best way to solve your problem is to write a script.
write a bash script including these commands.
give that script executable permission and then move it to /bin directory.
check whether the script is executing or not by the ./scriptname
then reboot and wola!!!! you have created a new command.
now no need for the ./scriptname, you can just type the name in the command line and it will work as any command like ls or cp or clear, etc.
