If rescue mode manages to mount your installed system on /mnt/sysimage
it automatically adds elements to the path including
/mnt/sysimage/bin:/mnt/sysimage/usr/bin:/mnt/sysimage/usr/sbin:/mnt/sysimage/sbin:/mnt/sysimage/usr/X11R6/bin,
so it depends on what you have installed.
Typing <Tab><Tab> at the command prompt after skipping the mounting or
removing the /mnt/sysimage elements of the PATH variable (e.g.
PATH=/bin:/usr/bin:/sbin:/usr/sbin) shows 438 available commands for the
5.2 DVD booted in rescue mode. Won't try to include them all here.
