Consider this program, compiled into `foo':
main(argc,argv,envp)
char **argv;
char **envp;
{
printf("argv[0] = %s\n", argv[0]);
exit(0);
}
and this script:
#! /room3/layer/foo
On Solaris:
ultra% ./foo.sh
argv[0] = /room3/layer/foo
On 2.2.14 (Redhat 6.1):
[layer@relay layer]$ ./foo.sh
argv[0] = foo
I have an interpreter of #! scripts that absolutely needs to know the
full path of where the executable is, and I can't assume it will be in
the user's path. Getting it in argv[0] is the cleanest way. That is,
I can tell users they have to use the full path in the #!, if they
want to use my interpreter.
I believe the behavior of #! on Solaris goes all the way back to BSD
in of the early 80's. FreeBSD 3.0 behaves as Solaris does.
I hope this considered a bug. If there willingness to take a patch for
it, I might work on making the fix.
