Fellow monks,

let's say there's a perl script /tmp/parse_me which has a she-bang line calling the perl interpreter and expects a file as an argument.

Now, when a script like

#!/tmp/parse_me

some text
[download]

gets called from the command line, the bash shell will call another instance of bash and hand it some text, which of course throws an error:

    ./scriptname: line 3: some: command not found
[download]

However, if the above script gets called in the zsh shell, it correctly calls

     /tmp/parse_me scriptname
[download]

and succeeds.

Does anyone know if there's a limitation in bash that only allows executables in the she-bang line, and prohibits using perl- and other scripts?
