running perl script in eshell on windows permission denied

running perl script in eshell on windows permission denied

[shul]

Hi,
I installed emacs on a windows machine that I am forced to use.
However when I try to execute a perl script that I am editing while in
the eshell
I get error message

./me.pl: Permission Denied

now i notice that
ls -l  me.pl
leaves me with
-rw-rw-rw 1 iis  5 810 Oct 17 11:25 me.pl

of course I can execute it in the M^X shell environment.

I tried chmod 777 me.pl
but it says
chmod: command not found

OK. So what can I do to execute some perl scripts from eshell?
I like eshell. It is so unix like...
Thanks
Mitchell

The least you could try is

$ perl me.pl

,but I guess there has to be a win32 equivalent to the unix chmod
command. But I don't know such things.

I would highly recommend you check out the cygwin environment, which
will bring you some semblance of a Unix environment.

Yes!

perl me.pl
works, which solves the real problem!

however i am still curious why the eshell environment creates a
'execute protection' that does
not exist in the native windows environment in the cmd.exe shell.
after all me.pl runs
in the cmd.exe shell and under M^X shell

I guess it may be
a carryover secondary to the universality of eshell, but it seems
strange, since there seems
to be no chmod command here..

thanks.

Also, I cannot install the cygwin environment. I actually am not even
allowed to install
emacs :).

The following function may be of some help here:
executable-make-buffer-file-executable-if-script-p
Don't know if it works in your environment though.

There is also a command called executable-chmod in perl-mode.
Hope that helps.
