shutdown command

I was setting up some aliases in my .bashrc file, but the system does not recognize them.

Code:

alias sd="shutdown -h 0"
alias rb="shutdown -r 0"

The system says it doesn't recognize the shutdown command.
I can see the man pages for shutdown on the same box.
This is screwy...
Does anyone know why this would happen?

Normal users don't have shutdown in their path, so shutdown can't be found. Use /sbin/shutdown and make sure you are allowed to use it as a normal user.

i understand how to set permissions on a file, but how would you do it on a command? is shutdown a program file? I no longer have my linux box in front of me, so i can not explore it.

for reboot, you can use "reboot" (available to users) and for shutdown... is in /sbin/shutdown, but has not user permissions, so you should change it.
Can you use also "shutdown -h 0" ?? cause i always use "shutdown -h now"....are they the same?

You can configure sudo to allow all normal users (or a group or single user or ...) to use shutdown (man sudo ;-).
The alias line then would be something like

alias sd="sudo shutdown -h 0"

now is with out any second delay.
0 means 0 second delay.
I'm not sure, but I would believe they would be the same.
unless it counts miliseconds prior to the 1st second.
I would believe it would be the same.
