Microsoft, since the early days of DOS, uses the two bytes carriage-return/linefeed as end-of-line terminators (and ^Z instead of ^D for EOF). So this isn't a Windows 7 specialty. But when copy-and-pasting lines, the command prompt isn't sent that 2 byte sequence, but an emulation of the enter key, where it's up to the program to handle that correctly. Cygwin comes with both vim and emacs (and a multitude of other editors) that let you save files in UNIX format.
You can leave out the shebang line if you really only use the bash shell. But expect your script to fail as soon as someone tries to run it in another shell (ksh/csh/ash/dash/...). By default, the script is executed using the same shell the user is currently running, but with the shebang line you'll tell the system explicitly which shell to use. This is especially useful if you use different scripting languages:
You can write stand-alone awk programs using
Perl programs will almost guaranteed fail if you run them without stating the interpreter somewhere
The same is true for expect, TCL, Python, Ruby, ....
The standard output for bash (just like any other POSIX shell) is stdout. If that is connected to a terminal, output goes there. If it's connected to a file, likewise. Maybe it's just that your awk statement didn't match, and so didn't print anything.

git-annex-shell
git-annex-shell(1) General Commands Manual git-annex-shell(1)NAME
git-annex-shell - Restricted login shell for git-annex only SSH access
SYNOPSIS
git-annex-shell [-c] command [params ...]
DESCRIPTION
git-annex-shell is a restricted shell, similar to git-shell, which can be used as a login shell for SSH accounts.
Since its syntax is identical to git-shell's, it can be used as a drop-in replacement anywhere git-shell is used. For example it can be
used as a user's restricted login shell.
COMMANDS
Any command not listed below is passed through to git-shell.
Note that the directory parameter should be an absolute path, otherwise it is assumed to be relative to the user's home directory. Also the
first "/~/" or "/~user/" is expanded to the specified home directory.
configlist directory
This outputs a subset of the git configuration, in the same form as git config --list
inannex directory [key ...]
This checks if all specified keys are present in the annex, and exits zero if so.
dropkey directory [key ...]
This drops the annexed data for the specified keys.
recvkey directory key
This runs rsync in server mode to receive the content of a key, and stores the content in the annex.
sendkey directory key
This runs rsync in server mode to transfer out the content of a key.
commit directory
This commits any staged changes to the git-annex branch. It also runs the annex-content hook.
OPTIONS
Most options are the same as in git-annex. The ones specific to git-annex-shell are:
--uuid=UUID
git-annex uses this to specify the UUID of the repository it was expecting git-annex-shell to access, as a sanity check.
HOOK
After content is received or dropped from the repository by git-annex-shell, it runs a hook, .git/hooks/annex-content (or hooks/annex-con-
tent on a bare repository). The hook is not currently passed any information about what changed.
ENVIRONMENT
GIT_ANNEX_SHELL_READONLY
If set, disallows any command that could modify the repository.
GIT_ANNEX_SHELL_LIMITED
If set, disallows running git-shell to handle unknown commands.
