Hi,

I have a properietary linux running on my server. System is
capable of running under low memory conditions.
I have a vi editor available on the system.

A proprietary linux? Is that possible?

I want to create a shell script wrapper over the actual vi command. I
am planning to verify available memory
before launching vi editor. So when somebody types vi command on the
shell prompt, it should invoke my wrapper
then my wrapper would invoke the actual vi editor after verification.

Name your script vi, rename the real vi or change PATH so your vi is
found first; do whatever tests you need and then
exec the_real_vi "$@"
.
