Piping to a python script
Hello,

I have a python script (not created by me), let's call it myscript, which I call with several parameters. If I don't provide the --password parameter, the script will ask the user to input the password.
So I run the script like this:
Code:
/wherever/myscript --username=whoever /some/other/path/parameter

That makes it ask for a password and wait for user input. If I enter the wrong password an error message will be displayed.
I want to pipe to this script some preset text to enter as the password, so that I can mimic entering an invalid password by hand.
Code:
echo 'wrongpassword' | /wherever/myscript --username=whoever /some/other/path/parameter

This unfortunately doesn't generate the same behaviour, as if it would be manually entered.
Can I simulate this behaviour with pipes/redirecting output? Why doesn't it work? I expect that the 'wrongpassword' text will be entered when the script asks for the password, but it seems I'm wrong.

Thanks!

sieveshell

SIEVESHELL(1)						User Contributed Perl Documentation					     SIEVESHELL(1)

NAME

       sieveshell - remotely manipulate sieve scripts

SYNOPSIS

       sieveshell [--user=user] [--authname=authname] [--realm=realm] [--password=password] [--exec=script] [--execfile=file] server[:port]

       sieveshell --help

DESCRIPTION

       sieveshell allows users to manipulate their scripts on a remote server.	It works via MANAGESIEVE, a work in progress.

       The following commands are recognized:

	   list list scripts on server.

	   put <filename> upload script to server.

	   get <name> [<filename>] get script. if no filename display to stdout

	   delete <name> delete script.

	   activate <name> activate script.

	   deactivate deactivate all scripts.

OPTIONS

       -u user, --user=user
	   The authorization name to request; by default, derived from the authentication credentials.

       -a authname, --authname=authname
	   The user to use for authentication (defaults to current user).

       -r realm, --realm=realm
	   The realm to attempt authentication in.

       -p password, --password=password
	   The password to use when authenticating to server. Note that this parameter can be seen in the process list. Use with caution!

       -e script, --exec=script
	   Instead of working interactively, run commands from script, and exit when done.

       -f file, --execfile=file
	   Instead of working interactively, run commands from file file and exit when done.
