this does seem to be an ambiguous area.
it seems more sane to allow arguments
to a script given to an interpreter on the
shebang line, passing everything after
"#!/interpreter [arg]" off for
"eval" or "sh -c" type parsing.
i don't know how it breaks anything to load execve's argv
with everything after the shebang, followed by command line
options/args. but it sure muddies the water if you don't.
otherwise there is a can of worms unnecessarily:
#!/bin/sh -x this is obviously ok.
#!/bin/sh -vx this is obviously ok too.
#!/bin/sh -c"string" this is currently not ok, but why shouldn't it be?
#!/bin/sh -c "string" this is currently not ok, but why shouldn't it be?
#!/bin/sh script this is obviously ok.
#!/bin/sh -n script this is currently not ok, but why shouldn't it be?
#!/bin/sh script 1 2 this is ok with FBSD and RH Linux,
but not ok in a few implementations,
but why shouldn't it be?
it seems that only a minority of execve() man pages / implementations
are preventing the sane solution ...
