USING AIX COMMANDS

                                   

USING AIX COMMANDS

AIX allows the use of several different shells. The main shells supported on the system are the Korn shell, the Bourne shell, and the C shell. The basic command interpretation is standard among these shells. However, each shell handles certain commands in a unique way. Therefore, the syntax section of the command will specify which shell syntax is being represented when differences occur. For example, {K} represents the Korn shell and {C} represents the C shell. Due to space restrictions, not all options will be specified with a command. Instead, only the more useful functions to a normal user are documented here. For more detail on the use of a command, use the man command or see the IBM AIX Commands References.
The syntax field uses some notation that may need to be clarified. Optional parameters are specified within square brackets '[' and ']'. A choice between options is denoted by a vertical bar '|'. Some options require that other options be specified on the command line. These options will be placed in braces '{' and '}' because their use is mandatory with certain options

GETTING STARTED

                          GETTING STARTED

Before you can use AIX, you must first login to one of the RISC workstations. A free machine should have a prompt saying login: on the screen. At this prompt, enter your userid. AIX will then ask for your password. Enter this into the computer, and if entered correctly, you will be logged onto the RISC terminal. AIX will then display your OS prompt and wait for your command. The OS prompt displayed depends on which command interpreter (shell) you are running and any configurations installed. The default is the K-shell which uses a $ as its OS prompt. Handouts are available for more information about each of the shells.

GENERAL INFORAMATION

GENERAL INFORMATION

AIX (version 3.2) is IBM's version of the UNIX operating system. AIX is the native operating system on the RISC System/6000 server and on the IBM RISC Model 220 workstations. These computers can be found in CCII-108 and in ENGR-124. AIX is a case-sensitive operating system, therefore the computer differentiates between upper and lower case letters.
