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:
