Much of this listing should be self-explanatory. Some points of interest are:
- The primary username is fbloggs, but they can also be reached on their student number alias.
- The User Identifier - your machine-understandable identity. It is also used by the UDB (User Database).
- The expiry date of your account (actually the latest expiry date of the "user classes" you belong to).
- See Account Classes and Groups for information on these fields.
- See Base Allocations for information on how your disk quota is allocated.
- This line may not be present, in which case the user is using the default login shell bash.
- Not used at present.
- The last time this user was sent an automatic warning ie. account status change/expiry.
- See Printing Quotas for information on how your print quota is allocated. Some users may also have a color print allocation, which will be listed under the main printer allocation.
Changing Your Username
See the Account Names FAQ page for more information.Changing Your Password
The command to change your password on unix is passwd. The system will prompt you to enter your current password, then a new one. Your chosen password will be checked against a password cracking program, and if it is too easy to crack you will have to try again. Use a mixture of upper and lower case letters, numbers and punctuation characters.To change your password on Windows, hold down the CTRL-ALT-DELETE keys together, and then select Change Password from the dialog box that appears.
Changing Your Login Shell
The default shell is bash. You can change this by typing chsh; you will be prompted for your password, then for the new shell. Type in the name of the shell you want to use; you don't need to enter a full path, just the name of the shell. The new shell will be instantiated the next time you login.The shells available are in /usr/local/bin:
- ae - pronounced `ash', a shell written by our very own Neil Brown.
- sh - the grand original Bourne shell.
- bash - the "Bourne again shell", from the GNU project.
- csh - the famous C shell.
- ksh - Korn shell.
- tcsh - Tenex C shell. Also known as Turbo C shell.
- zsh - Z shell.
Changing Your Path
Don't set PATH directly, always append or prepend a path. For example, to append /some/example/path to your path, do the following:In sh, ae, zsh, ksh, etc. , the following would go in your .profile
PATH="${PATH}:/some/example/path"
export PATH
In csh, tcsh, this would go in your .login
setenv PATH "${PATH}:/some/example/path"
