Can't use read() with shell.run()

local i = read()
if i == "AML help" then -- demonstrates usages
term.setTextColor(colors.red)
print("Usages: AML help <list or name> ")
term.setTextColor(colors.white)
os.run({},"internal/Anvil_Shell")
else
shell.run(i)
os.reboot()
end

Any custom 'commands' work, but doing shell.run(i) doesn't. I want to do this so that if i didn't specifically code a command, that it goes through the default, CraftOS shell.
Thanks in advance

Is this in an API or a program?

program

Then it should be fine. Is this the whole program? What kinds of test strings don't work, and what do they do instead of "working"?

if i were to write an input like "system profiler" which is recognized as a "command", it runs, or "NPaintPro", but anything else like, "edit <name>" (where it should go to the shell.run(i) line, it says, "attempt to index ? (a nil value)"

Your problem is that you are re-running your custom shell after each command. IIRC you should get a java error after entering 256 commands into the shell. shell.run line errors because you re-run your shell using os.run, passing an empty environment. shell is never loaded with os.loadAPI. It means that when your enter one command into your shell, shell API becomes unavailable for your program. You should really use an infinite loop.

Thanks, can't believe i didn't think of that!
