As Egor said, os.execute has changed from lua 5.2 onwards. It now returns 3 value, and you can get the underlying process return code by looking at the third return value. However, it seems -- on Linux, at least --, that the return code is the same as what would "echo $?" provide (a value between 0 and 255). Let’s go for the reverse shell as root. I added the nc reverse shell at the top of the script so the rev shell code can execute first.

If you’re on Linux, FreeBSD, or OSX, run the following script to download luvi and build lit and luvit for your platform: curl -L https://github.com/luvit/lit/raw/master/get-lit.sh | sh If you’re on windows, run the sister command in your cmd.exe command prompt (requires Powershell >= 3.0).

In most cases, you just want to install lit as quickly as possible, possibly in a Makefile or make.bat in your own library or app. We maintain several binary releases of luvi to ease bootstrapping of lit and While in a Linux terminal on a virtual machine, I came across a need to get a bash shell on a particular user, running Luvit repl.
