I have a program written in C and the command I am supposed to run it with on linux looks like this:
./program --something X Y
What exactly does that mean? I think X Y will be the arguments so argc[2]
will be X
and argc[3]
will be Y
?
But what about --something
?
Thanks a lot!

The C runtime does not discriminate any arguments, whether they start with --
or not. So you have,
argv[0] = "./program" argv[1] = "--something" argv[2] = "X" argv[3] = "Y" argv[4] = NULL
It is your program that assigns meaning to those values.
