As I already said, making internal call to libified part (perhaps in trailer.c) would make this part of conversation a moot point, but in general you can find argv_push(&child.args, "cmd2"); if (... some condition that involves variables parsed out ... ... by parse_options() of implementation of cmd1 ...) argv_push(&child.args, "--option-for-cmd2"); ... run_command(&child); in implementation of cmd1 that calls out to cmd2.
