dinosaur question: is there a command to alias another commend in a (3.13.8) startup file?

Hi all,

hoping to get to upgrading at least some stuff at some point, but
we're still running  mostly 3.13.8 on VxWorks 5.5.

A now retired former line manager of  mine implemented a shutdown
command that in addition to rebooting a crate also disconnects the
serial lines on it.
Now our telescope operators (all but one are new hires) have been
told to use shutdown but that  doesn't work on the crates where it
isn't loaded because the care doesn't have serial lines. I know of one
where we have to load code that is otherwise no longer used just
because of the shutdown function being embedded in it.
If there is and easy
alias shutdown reboot
I can put in the startup file (not a std.cmd file but a startup.vws
file  - for those who are only used to newer systems) that would be
great but neither Google's AI nor any recent documentation mentions
any of anything like this.

TIA,
Maren
(I may just have to teach the telescope operators, I guess)
