Yes, this is expected.
The following program shows how the args are passed in each case:
[EMAIL PROTECTED]:94]$ cat x.c
#include <stdio.h>
int
main(int argc, char *argv[])
{
int i;
for (i = 0; i < argc; i++)
printf("%d = \"%s\"\n", i, argv[i]);
}
[EMAIL PROTECTED]:95]$ ./a.out -s"" -b - 72
0 = "./a.out"
1 = "-s"
2 = "-b"
3 = "-"
4 = "72"
[EMAIL PROTECTED]:96]$ ./a.out -s "" -b - 72
0 = "./a.out"
1 = "-s"
2 = ""
3 = "-b"
4 = "-"
5 = "72"
[EMAIL PROTECTED]:97]$
In the first case, the shell concatenates -s and "" into a single arg,
and the -b gets interpreted as the separator etc.
