NAME

       rarun2 - radare2 utility to run programs in exotic environments

SYNOPSIS

     rarun2 [[script.rr2]]

DESCRIPTION

     This program is used as a launcher for running programs with different environment,
     arguments, permissions, directories and overridden default filedescriptors.

     The program just accepts a single argument which is the filename of the configuration file
     to run the program.

     It is useful when you have to run a program using long arguments or pass long data to stdin
     or things like that usually required for exploiting crackmes :)

DIRECTIVES

     The rr2 (rarun2) configuration file accepts the following directives, described as key=value
     entries and comments defined as lines starting with '#'.

     program     path to program to be executed

     stdout      select file to replace stdout file descriptor

     stdin       select file to read data from stdin

     input       set string to be passed to the program via stdin

     chdir       change directory before executing the program

     chroot      run the program in chroot. requires some previous setup

     preload     preload a library (not supported on Windows, only linux,osx,bsd)

     setuid      set process uid

     seteuid     set effective process uid

     setgid      set process group id

     setegid     set effective process group id

     setenv      set value for given environment variable

     arg[0-3]    set value for argument N passed to the program

EXAMPLES

     Sample rarun2 script

       $ cat foo.rr2
       #!/usr/bin/rarun2
       program=./pp400
       arg0=10
       stdin=foo.txt
       chdir=/tmp
       #chroot=.
       ./foo.rr2

     Connecting a program to a socket

       $ nc -l 9999
       $ rarun2 program=/bin/ls connect=localhost:9999

     Debugging a program redirecting io to another terminal

       ## open a new terminal and type 'tty' to get
       $ tty ; clear ; sleep 999999
       /dev/ttyS010
       ## in another terminal run r2
       $ r2 -d rarun2 program=/bin/ls stdio=/dev/ttys010
