http://cygwin.com/acronyms/#PPIOSPE, thanks!Yes, works if the second line too. Thanks for your patience. Here's a working version:

I think using 'igncr' should satisfy your complaints. If it doesn't, you need to tell use WHY (which, you'll notice, the OP failed to do).
So far, igncr hasn't worked for me either. I think this is because I don't know how to use it.
This is the simple shell script I'd like to have work (lines separated by CRLF):
#!/bin/bash echo helloworld
[snip]
I also tried editing the script (which I fear breaks it for non 3.x users of bash):
#!/bin/bash -O igncr echo helloworld
Did you try adding 'shopt igncr' to the script? This won't (shouldn't, at least!) break it for non-3.1-9 users (and if you stick a
2>/dev/null after it, won't print errors).
A ha! This form works in 3.1-9
shopt -s igncr; # #!/bin/bash echo hello world
Hmm, that should be the second line, not the first (not sure but I would guess the shebang is ignored when it isn't first). Does it still work that way, or does bash get confused about the CR on the shebang line? (If the latter, I would say this is a real bug that needs to be addressed somehow, or maybe igncr should affect the invoking bash's handling of the shebang).
#!/bin/bash shopt -s igncr 2>/dev/null; # please keep me on the second line, thanks echo hello world
You're right, sorry about that. The script succeeded in this case, too (returned 0).
But it apparently _does_ break for non-3.1-9 users:
rwalker@sycophant> ./helloworld.sh shopt: not found hello world rwalker@sycophant> bash --version GNU bash, version 2.05b.0(1)-release (i686-pc-cygwin) Copyright (C) 2002 Free Software Foundation, Inc.
It does? It looks like it did what it is supposed to do; gripe, and then correctly run the rest of the script. See my earlier suggestion about adding '2>/dev/null' after the 'shopt'.
