In one of our internal scripts (unix.run), I have noticed that the following shebang.

Any idea what the - in the magic number stands for ?

And what impact does it have on the script ?


Continuing on the same script, I have the following for unix.run

If I do a

it says 'Permission denied'

But if I run it as,

it works well.

Why the difference in behaviour between ./unix.run and sh unix.run?

Shouldn't it always say 'Permision denied' in both the cases ?

Any inputs/pointers on these two points, highly appreciated.

Thanks,
