I've a question about restart / shutdown my Fedora system using the terminal.
when I'm not using X, i can simply type "shutdown -r now" to restart my computer
but when i'm using X and typed the same thing under the terminal...
it said "bash: shutdown: command not found" Why ???
Also, the command "Service" seem not to work under the terminal
For example, when I'm not using X, i can type "Service iptables start" to start firewall
but when i'm using X and typed the same thing
it said "bash: service: command not found"
What exactly is "bash" ?
