Re: Force bash to start as administrator

Windows already has such a service. Try the following from your bash prompt:

and wait at most 60 seconds.

If you want an interactive login, omit the "Administrator" from the line above. Not sure if you'll need password, either (I don't on my W2K machine).
P.S. So much for Windows security, eh?
Ah, wouldn't that be Cygwin's login that was responsible for the [non]security? I believe it didn't prompt you for a password because Administrator in your /etc/passwd didn't have a password.

Why not simply use Runas?

This has been discussed before on this list but setting this up goes
something like this:

Type this in a bash window:
cygrunsrv -I LoginShell -d "Login shell" -p /usr/bin/cygstart -a
/usr/bin/login -e "CYGWIN=tty binmode ntsec"

Go to the Control Panel->Administrative Tools->Services
Right click on "LoginShell" and go to properties.
Go to the "Log On" tab and check the "Allow service to interact with

Follow this with this in a bash window:
cygrunsrv -S LoginShell

This will give you a new console window with the login prompt. From here,
you can log in as anybody, assuming you know the proper passwords. ;-)

You should be able to use ssh to do this as well, which should be easier
than going through the above gyrations.

Obviously, all this assumes that you can install a service or that one is
already installed for your use (ssh). Also, the above works on W2K. I
speak to other platforms, although it should be generally applicable to
NT-based platforms (with the possible exception of XP-Home).

The rest is obvious, no? ;-)

Subject: Force bash to start as administrator

I want to be able to start a bash shell as Administrator id=500 regardless
of who I am logged into the windows box as. Alternatively can I force cygwin
to ignore the current user credentials and use the Administrator.

I would like to be able to do this so that I can standardize my deployment
of Cygwin, I would like any user to always get the same permissions, same
home directory, etc.

BTW, how does login work in cygwin?
