The multiline gdb commands I tried to put as one string in gdb.execute and it didnt seem to like that either thats why they are multi commands. As for your proposed example I'll give it a try instead of using a break command (which is what my intention was with my code)

The " backtrace " command tells gdb to list all the function calls (that leads to the crash) in the stack frame. (gdb) backtrace #0 0x0017fa24 in _IO_str_overflow_internal () from /lib/tls/libc.so.6 #1 0x0017e4a8 in _IO_default_xsputn_internal () from /lib/tls/libc.so.6 #2 0x001554e7 in vfprintf () from /lib/tls/libc.so.6

step –> go to next instruction, diving into the function. list or l –> displays the code. print or p –> used to display the stored value. quit or q –> exits out of gdb. clear –> to clear all breakpoints. continue –> continue normal execution. 5.Now, type “l” at gdb prompt to display the code. 6. Let’s introduce a break point, say line 5.
Process Record and Replay (Debugging with GDB)
https://sourceware.org/gdb/onlinedocs/gdb/Process-Record-and-Replay.html
Set the requested ring buffer size for branch tracing in BTS format. Default is 64KB. If size is a positive number, then GDB will try to allocate a buffer of at least size bytes for each new thread that uses the btrace recording method and the BTS format. The actually obtained buffer size may differ from the requested size.

The -ggdb option to gcc will ensure that our debugging session using GDB will be a friendly one; it adds GDB specific debugging information to the test.out binary. We name this output binary file using the -o option to gcc, and as input we have our script test.c.

GDB Tracing Commands Tracing program execution: the record/playback model Some program behaviors can be analyzed only by collecting data over long periods of time for later analysis. Other problems occur in sections of code that are too time-sensative to be debugged interactively.

Executing under GDB control Here are the most common and often-used commands for controlling the execution of the kernel in GDB: s, step - Step through the program. If you want to go through your program step by step after it has hit a breakpoint, use the "step" command. Typing (gdb) s will execute the next line of code.
