Lightbulb tip: Simple script won't run in cygwin - vim editor involved
I ran into this issue and thanks to various postings in various forums, was
able to figure out the solution but didn't see one posting that laid the
whole issue out cleanly. So thought the following might help others ...

------------------------------------------------------------------------
The Problem
You use vim to create a simple shell script in a cygwin directory but the
script doesn't run properly. Example:

A script called test.sh:
#! /bin/sh
ls
echo "++++++"
cat a1.txt

produces this when run:
$ ./test.sh
./test.sh: line 2: $'ls\r': command not found
++++++
: No such file or directory

------------------------------------------------------------------------
The Solution
The problem is that vim has written the file in "DOS mode", which puts
an extra (as far as cygwin is concerned) carriage return (aka: control-M,
^M, \r) at the end of each line.

You can see that using the "-v" option with cat:
$ cat -v test.sh
#! /bin/sh^M
ls^M
echo "++++++"^M
cat a1.txt^M

The solution is to bring the file back into vi, set vim into binary mode with
the ":se binary" command, then save the file. Now, "cat -v" shows that
the carriage returns have been removed:
$ cat -v test.sh
#! /bin/sh
ls
echo "++++++"
cat a1.txt

And the program runs just fine:
$ ./test.sh
760log2trk.pl a1.txt spot.gpxcon.pl.rc
760log2trk.pl.rc a2.txt spot.gpxcon.tailers.kml
++++++
This is a file with a
few lines of text
in it.

------------------------------------------------------------------------
Note 1: The first line of the script file is common practice for a Unix script,
but isn't really required for the script to work in cygwin.

Note 2: Running the script by putting "./" in front of it is required in
cygwin as long as you don't have "." (the current directory) in the search
path. By default, cygwin doesn't include the current directory when looking
for commands. And for security reasons, it's not a good practice to put .
in your search path.

Note 3: Having saved the file in binary mode, you don't need to worry
about that setting for future edits of the file. vim will recognize the nature
of the file when it opens it and will keep it in that mode, so lines added
to the file will not be written with the carriage return. (vim tells you
that the file is in binary mode by putting "[unix]" after the file name
at the bottom of the window.)

vim-registry

vim-registry(5) 						    vim addons							   vim-registry(5)

NAME

       vim-registry - syntax for vim-addons registry files

SYNOPSIS

       PACKAGE-NAME.yaml

DESCRIPTION

       A  registry file is a multi-document YAML file (i.e. it can be composed by several different YAML documents separated by "---" lines). Each
       YAML document represents a registry entry, that is the information describing a single addon.

       Ideally, the registry directory contains one file per package shipping addons; with a filename obeying to the convention PACKAGE-NAME.yaml.
       Hence a single package can contribute to the registry with multiple entries described in a single YAML file.

       For example, the "vim-scripts" package should ship a single /usr/share/vim/registry/vim-scripts.yaml file, containing one YAML document per
       shipped addon. The first lines of such file can look like the following:

	   addon: alternate
	   description: "alternate pairing files (e.g. .c/.h) with short ex-commands"
	   basedir: /usr/share/vim-scripts/
	   disabledby: "let loaded_alternateFile = 1"
	   files:
	     - plugin/a.vim
	     - doc/alternate.txt
	   ---
	   addon: whatdomain
	   description: "query the meaning of a Top Level Domain"
	   basedir: /usr/share/vim-scripts/
	   disabledby: "let loaded_whatdomain = 1"
	   files:
	     - plugin/whatdomain.vim
	   ---

       Each registry entry may contain the following fields, to be typeset according to the YAML specification:

       addon (Required)
	      Name of the addon.

       description (Required)
	      Human understandable textual description of the addon.

       files (Required)
	      List of the files which compose the addon and are required to be present in a component of the Vim runtime path for the addon to	be
	      enabled.	Each file is specified relative to a component of the Vim runtime path.

       basedir (Optional)
	      Directory  where the files shipped by the addon (i.e., where the symlinks of the user/sysadm should point to) reside on the filesys-
	      tem.  Default is /usr/share/vim/addons.

       disabledby (Optional)
	      Vim script command that can be used (usually by adding it to ~/.vimrc) to prevent  the  addon  from  being  used	even  when  it	is
	      installed.  The intended usage of this field is to "blacklist" an undesired addon whose files are available, and hence automatically
	      loaded by Vim, in a component of the Vim runtime path.
