Use getconf instead of bootinfo

Technote (FAQ)


Question

The bootinfo command does not have a man page, can I use it?

Answer

The command /usr/sbin/bootinfo has traditionally been used to find out information regarding system boot devices, kernel versions, and disk sizes. This command has been deprecated in favor of the command /usr/bin/getconf.

The bootinfo man page has been removed, and the command is only used in AIX by the booting and software installation utilities. It should not be used in customer-created shell scripts or run by hand.

The getconf command will report much of the same information that bootinfo will. Below are some examples of variables which can be queried. The full list is on the getconf man page.
