RZ_RUN(1) General Commands Manual RZ_RUN(1) NAME rz-run -- rizin utility to run programs in custom environments SYNOPSIS rz-run [directives | script.rz] [-- program [args]] DESCRIPTION This command is part of the Rizin project. This program is used as a launcher for running programs with different en- vironment, arguments, permissions, directories and overridden default file descriptors. -l List all the supported profile directives. -t Output a base template profile. Try rz-run -d > profile.rz -w Show the terminal name and wait for a connection from another process. Try rz-run stdio=<ttypath> program=/bin/sh The program accepts a single argument which is the filename of the configu- ration 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 rrz (rz-run) configuration file accepts the following directives, de- scribed as key=value entries and comments defined as lines starting with '#'. arg[0-511] Set value for argument N passed to the program aslr Enable or disable ASLR bits Set 32 or 64 bit (if the architecture supports it) chdir Change directory before executing the program chroot Run the program in chroot. requires some previous setup core Set no limit the core file size connect Connect stdin/stdout/stderr to a socket pty Use a pty for connection over socket (with connect/listen) envfile Set a file with lines like `var=value` to be used as env fork Used with the listen option, allow to spawn a different process for each connection. Ignored when debugging. input Set string to be passed to the program via stdin libpath Override path where the dynamic loader will look for shared li- braries listen Bound stdin/stdout/stderr to a listening socket maxstack Set the maximum size for the stack maxproc Set the maximum number of processes maxfd Set the maximum number of file descriptors nice Set the niceness level of the process preload Preload a library (not supported on Windows, only linux,osx,bsd) daemon Set to false by default, otherwise it will run the program in background, detached from the terminal. program Path to program to be executed pid Set to true to print the PID of the process to stderr pidfile Print the PID of the process to the specified file runlib Path to the library to be executed runlib.fcn Function name to call from runlib library rzpreload Preload with librz, kill -USR1 to get an rizin shell or -USRZ to spawn a webserver in a thread setenv Set value for given environment variable setegid Set effective process group id seteuid Set effective process uid setgid Set process group id setuid Set process uid sleep Sleep for the given amount of seconds stdio=value Set io streams (stdin, stdout, stderr) to a value stdio=!cmd Redirect input/output to the process created by the specified command stdin Set stdin, stdout, and stderr streams to the specified value stdout Select file to replace stdout file descriptor stderr Select file to replace stderr file descriptor system Execute the given command timeout Set a timeout timeoutsig Signal to use when killing the child because the timeout hap- pens unsetenv Unset one environment variable VALUE PREFIXES Every value in this configuration file can contain a special @filename Slurp contents of file and put them inside the key text Escape characters useful for hex chars 'string' Escape characters useful for hex chars !cmd Run command to store the output in the variable :102030 Parse hexpair string and store it in the variable :!cmd Parse hexpair string from output of command and store it in the variable %1234 Parses the input string and returns it as integer EXAMPLES Sample rz-run script $ cat foo.rrz #!/usr/bin/rz-run program=./pp400 arg0=10 stdin=foo.txt chdir=/tmp clearenv=true setenv=EGG=eggsy setenv=NOFUN=nogames unsetenv=NOFUN # EGG will be the only env variable #chroot=. ./foo.rrz Connecting a program to a socket nc -l 9999 rz-run 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 rizin $ rizin -r foo.rrz -d ls $ cat foo.rrz #!/usr/bin/rz-run stdio=/dev/ttys010 ## Or you can use -R to set a key=value rizin -R stdio=/dev/ttys010 -d ls You can also use the -- flag to specify program and arguments in a more natural way: rz-run timeout=2 file ... -- sleep 4 Run a library function rz-run runlib=/lib/libc-2.25.so runlib.fcn=system arg1="ls /" SEE ALSO rizin(1), rz-asm(1), rz-bin(1), rz-diff(1), rz-find(1), rz-gg(1)i1/4 rz- hash(1) AUTHORS pancake <pancake@nopcode.org> byteninjaa0 FreeBSD ports 15.quarterly January 24, 2024 RZ_RUN(1)
