One complication with getopt is that the xargs options and the commands
arguments should be kept seperate.
echo "one" | xargs grep -i fred
-i is a grep option, not xargs option, this is currently broken in
Im working on an alternative patch, first part of which is.
+ int argc_xargs;
+ /* Determine how many arguments are for xargs */
+ for (argc_xargs = 1; argv[argc_xargs] && argv[argc_xargs] == '-'; argc_xargs++);
bb_opt_complementaly = "pt";
- a = bb_getopt_ulflags(argc, argv, "tpr");
+ a = bb_getopt_ulflags(argc_xargs, argv, "tpr");
