Quick and dirty way to solve your issue -
$ tr -d '\r' > script.fixed < script.erring
> This was pretty perplexing,
It is actually pretty clear, though.
$ od -t x1a < script.erring
See the output.

Re: Another confusing error from someone else's Cygwin setup
The line endings were the issue, thanks. They were that way because I
didn't realize I should force those files in git to have eol=lf in a
.gitattributes file. This is now all fixed.

If you run bash with the "-o igncr" option, it will ignore extraneous
carriage return characters.
But the characters are there in the first place because your
script has been converted into using Windows line endings:
carriage return + linefeed.
You didn't say how the script was transferred, but lots
of programs could add returns when you transfer something
to windows: git or ftp just to name a few.
You both could try running "bash --version". The first line should
say something like
"GNU bash, version 5.2.15(3)-release (x86_64-pc-cygwin)"
Note the "pc-cygwin" at the end.
HTH,
Mike Gran

Apologies, I don't remember your other report, but this one kind of
sounds like an end-of-line characters problem. Try installing
(Cygwin's) dos2unix, if you don't already have it, then try running
dos2unix on the script. If it still doesn't work, try then running
unix2dos. If you have binutils installed, you can also use the 'file'
command for a quick report on whether files have lines terminated with
CR (macOS), CRLF (Windows), or LF (UNIX/Linux). 'file' might not
realize when you have files with inconsistent line-terminators, though.
And I forgot dos2unix also includes a 'mac2unix' command these days
(though not a mac2dos), so maybe try that first.

Another confusing error from someone else's Cygwin setup
I'm seeing a problem with someone else's Cygwin setup, sort of similar to a
problem I asked about a couple of weeks ago, in that it's a problem with
the same user, but seemingly a completely different problem.
He is using a Bash script that I wrote, and he gets a seemingly nonsensical
error that I don't understand.
The script starts out pretty simply, just like this:
--
#! /bin/bash
#set -x
main() {
if [ "$1" == "" ]; then
usage;
exit;
fi
...
-
He was getting a weird error on line 3, just saying this:
-
...: line 3: syntax error near unexpected token `$'{\r''
...: line 3: `main() {
---
This was pretty perplexing, so I asked him to uncomment the "set -x" line
to see if that provided any useful information, and that fails with a
different error:
---
: invalid option...: line 2: set: -
set: usage: set [-abefhkmnptuvxBCEHPT] [-o option-name] [--] [-] [arg ...]
--
This also makes no sense to me. I compared our "uname -a" outputs, and
they are almost identical. However, I then had him run "bash --version",
and I compared it to mine. Ironically, I'm using an OLDER version of bash
than he is. I'm on v4.4.12(3)-release, and he's on v5.2.15(3)-release. Is
there something in 5.x versions of Bash that could cause these issues?
