how to embed shell script within a .BAT file

how to embed shell script within a .BAT file

[Nellis, Kenneth]

I'm tired of creating pairs of script files:  a clickable .BAT file 
to invoke my shell script and then my shell script to do the actual
work. I was wondering if any of the geniuses on this list have come 
up with a way to embed a shell script inside a clickable .BAT file.

A quick google search for "polyglot shell bat" finds:

Worst solution I've never seen. Starting from obvious limit of nine parameters
and down to the less-than-manageable code gibberish.

Something like this might do.  It assumes you know the path to the
Cygwin bin directory.  Passing in arguments would be a bit more work and
would probably be somewhat limited unless you have a small number of
possible arguments.

FYI, I don't have a Windows system readily available anymore, so this is
untested.

Shelly.bat:

@echo off

rem Put Cygwin bin directory into PATH
set PATH=C:\cygwin\bin;%PATH%

type %0 | sed "0,/^---BASH SCRIPT FOLLOWS---/ d; s/\r*$//" | bash
goto :eof

---BASH SCRIPT FOLLOWS---
echo $SHELL is alive
^Z

[Eliot Moss]

Do you really need to embed the script *within* the file?
It would be straightforward to *invoke* a script from the
file by something along the lines of:

bash -c script

in the .bat file ... Eliot Moss

Thanx to Jeremy, Andrey, and the others who responded.

Jeremy's solution is closest to what I was looking for; however
I need it to work from a networked, non-drive-mapped folder. 
(CMD.EXE doesn't like UNC paths.) I hadn't realized that I could
pipe a script into bash.

Andrey also suggested something that allows Windows-clickable
script files, a strict requirement, bypassing the stated, but
unnecessary requirement that it be a .BAT file, by associating 
a file type with bash. This would bypass the UNC issue, so may 
end up being the best solution for me.

The solution to the UNC path problem is to put something

PUSHD %~dp0

near the beginning of the script.  That is if you really want to have
.bat files and click on them in Explorer.  Associating the shell scripts
properly so that Explorer will hand them to Cygwin sounds like a better
solution to me.

BTW, works great! Here's the completed .BAT file preface with added error
handling so the CMD window doesn't auto-close if the bash code exits with
an error.

@echo off
set PATH=C:\cygwin64\bin;%PATH%
PUSHD %~dp0
type %0 | sed "0,/^---BASH SCRIPT FOLLOWS---/ d; s/\r*$//" | bash
if errorlevel 1 pause
exit

---BASH SCRIPT FOLLOWS---
...

I'll pursue associating a shell script with a file type
when I have more time.

PUSHD "%~dp0"

But be aware, that you will lose the ability to run such script from different
CWD.

> type %0 | sed "0,/^---BASH SCRIPT FOLLOWS---/ d; s/\r*$//" | bash

sed "0,/^---BASH SCRIPT FOLLOWS---/ d; s/\r*$//" < "%~f0" | bash

That's nice for desktop application.
But

EXIT %ERRORLEVEL%

would be more useful in general.

And keep in mind: not everything can be run that way, unfortunately.
Only interpreters accepting command stream from STDIN (such as bash).
And you will lose the ability to pipe data to such script yourself.

On a slightly unrelated note, please avoid naming your scripts ".bat", when
you are using extended CMD features. Not every .bat file interpreter supports
a full range of bugs in CMD.

reg ADD "HKEY_CURRENT_USER\Software\Microsoft\Command Processor" /f /v "DisableUNCCheck" /t REG_DWORD /d 1

And speaking of "doesn't like", it only don't like it's own CWD to be UNC path.
You can still start programs by full UNC path from CMD.
Though, with correct settings (see above), the point is moot.

I always thought it odd that MS invents UNC's then fails to support them 
properly in their own tools.

Try pushd on a UNC path...

Since migration to Win7, I'm using native symlinks, and pretty happy about it.
I still occasionally hit the UNC path here and there from old shortcuts, but
overall, it's all "local" filesystem. :b

google: cygwin shell wrapper script
I posted mine in the mailing list not once, and it's not the only available
solution.

It is technically possible to invoke specific processor for a bat file, but no
Cygwin tools understand the necessary syntax. Your only option is to create
proper association(s) for your favorite extensions.

FTYPE unixshell.script="C:\Programs\Cygwin_64\bin\env.exe" -- /bin/cygwrap.sh "%1" %*
ASSOC .sh=unixshell.script
ASSOC .awk=unixshell.script
ASSOC .pl=unixshell.script
ASSOC .whatver=unixshell.script

The wrapper is as simple as

-------->8-------->8-------->8-------->8--------
#!/bin/sh

test -z "$1" && exit 1

/bin/env -- "$(cygpath -au "$1")" "${@:2}"
--------8<--------8<--------8<--------8<--------

Don't forget to add your favorite extensions to PATHEXT, else you won't be
able to run them scripts from CMD.

I'm curious.  Why go through all of what you wrote when all you need to do
is execute the shell script?  I'm a Z-shell user and have a bunch of scripts
that I run.

Maybe the secret is not to try and start a script from within a command prompt.
Start cygwin xterms.  I have two that I start up after booting the system.
The scripts are in my home/bin path, so they are found.

It is as simple as that.

It is true that they are not "clickable," but entering the script name in
the xterm also allows me to also include parameters/options.

Scripts aren't executed in vacuum. And the question is not limited to SHELL
scripts.

Why? I don't need no friggin xterm, I need to run a script.
Is this a hard concept to grasp?

Simple as what?
I don't understand, what "two" you have and what you are actually doing.

I don't know the name, I have a script that I want to run. Here. Now. Why
can't I just click it?

True.  I do not compile any programs, so anything that I need to run that
is clickable are Windows programs.

It is not, which I how I run my scripts, from an xterm command prompt.
All of my scripts have have input, be it an option and/or file to work on.
That is not easily done if the script were clickable.  Sure, the script
can ask for input, but that adds time to get it running.  Starting it via
the command line saves me lots of time.

I also have scipts that are started via cron.  Options are passed to the
scripts from within the scron configuration file.

Two xterms that are started by clicking on the shortcut that I created that
points to the BAT file that starts an xterm.

You never have to supply your scripts with options and/or files to deal with?

Entering the script name in the xterm is a lot faster than hunting down the
name in explorer (the file manager) or a shortcut on the desktop.  If you
have a lot of scripts, your desktop can get cluttered real fast.  Mine is
cluttered enough with Windows programs that I use.

I'm and old Unix guy that has grown up with the command line.  I find it
fast to use.  There are those that hate the command line and prefer to
onlty click on something to get it started.

I guess that is where we differ.

I've provided you with an option.  Do with it as you will.

Isn't this as simple as adding the path to cygwin/bin to PATH and
executing the commands you need?

Or associate .sh extension to cygwin/bin/bash.exe then clicking will
associate the correct shell.
