Hi,
Can someone explain why the "-c" option of /bin/sh  behaves strangely ?

hp-ux>   ksh  		-c 'echo $*' 1 2 3 4 5
1 2 3 4 5
hp-ux>   (posix) sh	-c 'echo $*' 1 2 3 4 5
1 2 3 4 5
sunos4>  /bin/csh  -f	-c 'echo $*' 1 2 3 4 5
1 2 3 4 5
sunos4>	 /bin/su - any  -c 'echo $*' 1 2 3 4 5
1 2 3 4 5
sunos4>	 /bin/su   any  -c 'echo $*' 1 2 3 4 5
1 2 3 4 5


But,

hp-ux>   /bin/sh -c 'echo $*' 1 2 3 4 5
2 3 4 5
sunos4>  /bin/sh -c 'echo $*' 1 2 3 4 5
2 3 4 5

sunos4>  /bin/sh -c 'echo $0 $*' 1 2 3 4 5
1 2 3 4 5

..........why??   Can I find the reason in some FAQ articles ?
