I am trying to modify the login shell in /etc/passwd to be a shell script i=
nstead of a binary file so I can modify the commands sent non-interactively.

However, when I do so, I get the following error when logging in via ssh or=
 "su - username":
 - /bin/newcmd.sh: Bad file descriptor

Where /bin/newcmd.sh is the script that I am trying to run.

The script itself runs OK when executed from a cygwin bash prompt and I'm n=
ot sure what I'm doing wrong.

Does anyone know how I can use a script as a login shell?

Can anyone point me to some documentation on how the login process works fo=
r Cygwin? I'm having trouble understanding exactly how things are supposed =
to work and what parts of the login process I could modify.

Thanks,

Tim
