Works from bash prompt, but not from script!

Shell Programming and Scripting
1

I'm trying to use unison from bash on windows with cygwin. I don't know if this is a cygwin question, bash question or unison question. Since I always get reprimanded by the cygwin mailing list for assuming it is a cygwin problem, I'll assume it is a bash question.

The following commands work from the bash command prompt:

cp /cygdrive/c/.emacs .
cp /cygdrive/c/.viper .
ls
unison "/cygdrive/c/busines" "busines"

However, when I put them in a bash script and chmod +x backup.bash I get the following errors:

Incidentally, I'm editing using emacs and emacs is not showing any control characters. So I'm mystified where bash is complaining about '\r'!

Also, the line numbers don't align correctly because I deleted a lot of comments.

What am I doing wrong?
Thanks,
Siegfried

please post the whole script.... and use "set -xv" in your script to see more debug information at runtime...

Really should include the shebang #!/bin/bash, or what have you, in all your scripts. Putting an extension of .bash doesn't do anything in this case.

I just when back to the script file and noticed that someone has inserted ^M at the end of each line! Hmmm... This could explain some of those error messages. While this is still a bash question, it might be a windows problem. Is there a way to make bash tolerate the ^M?

Here is the entire file:

#!/usr/bin/bash
#
# Begin commands to execute this file using bash with bash
# chmod +x backup.bash
# ./backup.bash
# End commands to execute this file using bash with bash
#
# $Log$
#
set -xv
cp /cygdrive/c/.emacs .
cp /cygdrive/c/.viper .
ls

Here are all the error messages again after I ran it again after remove the ^M at the end of each line.

use "dos2unix" to delete the ^M

Thanks for the good infos.

Thanks. Good infos

Yup-- that worked. Emacs was telling me there were no \r but apparently there were because dos2unix worked (even on windows).

Thanks,
Siegfried
