您可以使用getopt。
#include <ctype.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> int main (int argc, char **argv) { int bflag = 0; int sflag = 0; int index; int c; opterr = 0; while ((c = getopt (argc, argv, "bs")) != -1) switch (c) { case 'b': bflag = 1; break; case 's': sflag = 1; break; case '?': if (isprint (optopt))fprintf (stderr, "Unknown option `-%c'.n", optopt); elsefprintf (stderr, "Unknown option character `\x%x'.n", optopt); return 1; default: abort (); } printf ("bflag = %d, sflag = %dn", bflag, sflag); for (index = optind; index < argc; index++) printf ("Non-option argument %sn", argv[index]); return 0; }
