There is no command specific to SSH. Whether you are physically using the machine in question or using an SSH client the process is the same. On Ubuntu, one is encouraged not to use the root account directly. To execute a command as root, enter sudo
su (will change user to root)sudo command (will run command as root)
sudo will run a command with root privileges
Either login as the root user or type: sudo then the command you wish to run.
When u put sudo before a command in terminal the command run with root privileges
The root directory is indicated by a "/'. You can navigate to the root directory using the command 'cd /'.
Enter this command as root: "apachectl start"
chmod but only if you are root, or logged in as the user and group shown when you do ls -l shokeenda See man chmod for its usage
For Unix/Linux, use the command 'cd /' For Windows, you can also use the same command or 'cd \'
No, none of the passwords used in a Linux system can be "recovered" because there isn't a reverse encryption for it. However, you can "reset" the root password by using the single-user mode at boot time (which puts you in the root account automatically) and then changing at that time.
For Unix/Linux, use either the 'sudo' command or 'su' to the root account.
"cd /" will move the user to the root directory, assuming the user has permission to move to this directory, and the user has not been chroot'ed to a specific directory (which will cause "cd /" to move the user to that named directory, instead of the system's root).
Virtually all Linux distributions will accept the "halt" command. Some also have a shutdown command, though this has additional parameters and is meant mainly to shut down the system at a certain time.
