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.
