Use the list-menu subcommand of the bootadm command to list the GRUB menu entries that are currently on the system. This information is supplied by the grub.cfg file. Use either the list-menu or show-entry subcommand to show information about specific menu entries. You can select specific entries by the entry number using the –i option or by title using the –t option.
Example 1 Listing All Items in the GRUB MenuYou can use the list-menu subcommand to see the contents of the current GRUB menu. The subcommand also displays the location of the boot loader configuration files, the default boot entry number, the autoboot-timeout value, and the index number and title of each boot entry.
$ bootadm list-menu the location of the boot loader configuration files is: /rpool/boot/grub default 0 console graphics timeout 30 0 Oracle Solaris 11 FCS 1 Oracle Solaris backup-1 2 Oracle Solaris 11 11.2Example 2 Listing Information About a Specific Entry Number
If you specify an entry number with the –i option when running the list-menu subcommand, the output displays the information about the selected entry.
$ bootadm list-menu -i 0
the location of the boot loader configuration files is: /rpool/boot/grub
title: Oracle Solaris 11 FCS
kernel: /platform/i86pc/kernel/$ISADIR/unix
kernel arguments: -B $ZFS-BOOTFS -v
boot archive: /platform/i86pc/$ISADIR/boot_archive
ZFS root pool: rpool
The same information, without the location of the boot loader configuration files is displayed if you use the show-entry subcommand with the –i option.
$ bootadm show-entry -i 0
title: Oracle Solaris 11 FCS
kernel: /platform/i86pc/kernel/$ISADIR/unix
