Question

My embedded device uses busybox and it only has getopt. I wanted to port getopts to my embedded device and was looking for getopts source to do that. Where can I find getopts source?

Answer 1

You should find it in bash source. You can download bash from Here

You will find getopts.def inside builtins/ dir.
mkbuiltins -D . getopts.def will create getopts.c.
You will have to do configure and make which will create mkbuiltins
inside builtins/ directory.
