From: "Khimenko Victor" <khim@sch57.msk.ru>
It's possible to specify optional argument to interpreter in script: -- cut -- #!/usr/bin/perl -w -- cut -- but not possible to specify two arguments -- cut -- #!/usr/bin/eperl -B=<!--eperl -E=--> -- cut --
Why ? It's very annoying :-(( What POSIX says on subject ?
Why?
It is like this: if you have a script called bar, that starts with
#!/some/patch/foo lots of arguments
and the script is invoked using
/some/other/path/bar
then the program /some/patch/foo is called with precisely three arguments: 0: "foo" 1: "lots of arguments" 2: "/some/other/path/bar"
In other words: a space does not separate arguments here. See also fs/binfmt_script.c.
POSIX? "Some systems can exec shell scripts. This functionality is outside the scope of this document."
