viewing all the commands

i was using redhat previously and while using shutdown command works fine .

now i am using fedora but it displays

[root@localhost user]# shutdown
bash: shutdown: command not found

so is there any way to view all the commands that is supported by the shell.

Thanks

shutdown will be root only - confirm by using the absolute path /sbin/shutdown (guess it's there in Fedora!)

use sudo if you want users to be able to shutdown or maybe su - -c shutdown -h now

shutdown is available in /sbin/ but i cant see it in console while pressing tab to view all commands

Using the shell's tab completion will display all of the commands available by searching your path (type echo $PATH). If the /sbin directory is not on your path, then the commands in that directory won't be listed. I haven't used Fedora for a while, but it may be that the path for root is set in /etc/profile as it is in Slackware. Have a look in there and add /sbin if necessary.

AS gilead said, the /sbin won't be in PATH variable by defalut. this /sbin will be available only to the root user.

so if you want to give access to the commands under /sbin to the normal user, add /sbin in PATH variable in .bashrc of the home directory of the user

Judging by the first post, it was the root account being used. I thought that was unusual - root has /sbin in the path on all of my boxes.
