How to run the program using the debugger ##

r2 -d /bin/ls - start in debugger mode => []

How do I attach/detach to running process ? (gdb -p) ##

r2 -d <pid> - attach to process

r2 ptrace://pid - same as above, but only for io (not debugger backend hooked)

[0x7fff6ad90028]> o-225 - close fd=225 (listed in o~[1]:0)

r2 -D gdb gdb://localhost:1234 - attach to gdbserver

How to set args/environment variable/load a specific libraries for the debugging session of radare

Use rarun2 (libpath=$PWD:/tmp/lib, arg2=hello, setenv=FOO=BAR ...) see rarun2 -h / man rarun2

How to script radare2 ?

r2 -i <scriptfile> ... - run a script after loading the file => []

r2 -I <scriptfile> ... - run a script before loading the file

r2 -c $@ | awk $@ - run thru awk get asm from function => []

How to list Source code as in gdb list ?

CL @ sym.main - though the feature is highly experimental

Equivalent of "set-follow-fork-mode" gdb command

This can be done using 2 commands:

dcf - until a fork happen
then use dp to select what process you want to debug.
