How do I pass a command line argument while starting up GDB in Linux? [duplicate]

Answer 1

Another option, once inside the GDB shell, before running the program, you can do

(gdb) set args file1 file2

and inspect it with:

(gdb) show args

Answer 2

Try

gdb --args InsertionSortWithErrors arg1toinsort arg2toinsort

Answer 3

Once gdb starts, you can run the program using "r args".

So if you are running your code by:

$ executablefile arg1 arg2 arg3 

Debug it on gdb by:

$ gdb executablefile  
(gdb) r arg1 arg2 arg3

Answer 4

I'm using GDB7.1.1, as --help shows:

gdb [options] --args executable-file [inferior-arguments ...]

IMHO, the order is a bit unintuitive at first.
