Use the command 'passwd'
passwd
The 'CD' command is not standard for Unix. The 'cd' command, however, will change directories (folders). It is a means of navigating the Unix file system.
passwd
Super User! That allows you to assume full control over the system (Linux/Unix) when you log on as a regular user. You'll need a password.
You can log in via telnet or ssh protocol for a command line prompt environment to Unix, or you can use a graphical user interface such as KDE or Gnome, or the CDE environment via X-windows. In any of these protocols, you must supply a username and password to successfully log into the Unix system.
Use the 'mkdir' command
There is no traditional 'execute' command in Unix.
If you are the user wishing to change your password then use the 'passwd' command, or if you are on an NIS based system use 'ypasswd'. As root you can change anyone's password by adding thier login name to then end, eg to change tom's password use passwd tom. It is not a good idea to login as root and so sudo has been created which allows configured access to root commands by other users; if this case and you are so privileged (as an administrator), you would use: sudo passwd tom
There is a command called useradd in Linux which you can use to add a new user. Here's an example 1. Add the user (you need to be a superuser to run this command) # useradd test 2. Set the password # passwd test Changing password for user test. New UNIX password: Retype new UNIX password: passwd: all authentication tokens updated successfully.
There are many ways to do this, but the fastest and easiest is to use the 'uptime' command, which will tell you in a summary line how many users are logged in.
Most people set up their shell to give them an indication in the command prompt. But this isn't "built in" (the mechanism for doing so is built in to most shells, but you can use the same mechanism to change the prompt to pretty much anything you want).The command pwd on a Unix system should tell you "where you are".
There is no standard 'format' command in Unix.
