Following Alcides‘ post Unix in Scala I spent a few minutes doing the same with 9 lines of code using Lua and no $voodoo involved.

print ("You have mail")

while true do

     io.stdout:write ("$")

     c1 = io.stdin:read()

     if c1 == "uname"

          then print ("Lunix 0.1 (Lua)")

          else print ("Command " .. c1 .." not found.")

     end

end

Needless to say that his is in no way serious, it’s just silliness like Songs in Code (which I failed to participate in, but eh… the night is young) and i’m sure that reducing unix to three lines of interaction is going to offend a few people.

Lua came into play when I felt the need to change a few nmap scripts to suit my needs. It’s been really fun working with it even though it’s a bit hard to find good documentation about it on the web. Which reminds me… my amazon wishlist has one or two books on Lua. Hey, just saying…
