65 Migration from IDA, GDB or WinDBG
65.1 How to run the program using the debugger
rizin -d /bin/ls
- start in debugger mode => [video]
65.2 How do I attach/detach to running process (gdb -p)?
rizin -d <pid>
- attach to process
rizin ptrace://pid
- same as above, but only for io (not debugger backend hooked)
[0x7fff6ad90028]> o-225
- close fd=225 (listed in o~[1]:0
)
rizin -D gdb gdb://localhost:1234
- attach to gdbserver
65.3 How to set args/environment variable/load a specific libraries for the debugging session of rizin?
Use rz-run
(libpath=$PWD:/tmp/lib
, arg2=hello
, setenv=FOO=BAR
…) see rz-run -h
/ man rz-run
65.4 How to script rizin?
rizin -i <scriptfile> ...
- run a script after loading the file => [video]
rizin -I <scriptfile> ...
- run a script before loading the file
rizin -c $@ | awk $@
- run through awk to get asm from function => [link]
[0x80480423]> . scriptfile
- interpret this file => [video]
[0x80480423]> #!c
- enter C repl (see #!
to list all available RLang plugins) => [video], everything have to be done in an oneliner or a .c file must be passed as an argument.
To get #!python
and much more, just build rizin-bindings
65.5 How to list Source code as in gdb list?
CL @ sym.main
- though the feature is highly experimental

66.1 Equivalent of “set-follow-fork-mode” gdb command
This can be done in two ways:
- Use the configuration variable
dbg.follow.child
to choose the process (parent or child) you want to follow. - Use
dcf
to debug until a fork and then usedp
to select what process you want to debug.
