To find out CPU information, including the clock speed, on an AIX UNIX system, you can use the lscfg command.
The lscfg command is a utility that displays hardware configuration information for the system.
To display CPU information, you can use the -vp option with the lscfg command. For example:
lscfg -vp
This will display a list of hardware devices and their configurations, including the CPU.
You can find more information about the lscfg command and its options in the AIX documentation or by running the lscfg --help command.
To display only the CPU information, you can use the grep command to filter the output of the lscfg command. For example:
lscfg -vp | grep "Processor"
This will display only the lines that contain the word "Processor" in the output of the lscfg command, which will include the CPU information.
You can find more information about the grep command and its options in the AIX documentation or by running the grep --help command.
Keep in mind that the clock speed of a CPU may vary depending on the workload and power management settings of the system. The clock speed reported by the lscfg command may not reflect the actual clock speed of the CPU at a given moment.
