Bash scripts are no longer portable?


I wrote a bash script that runs fine on a default SuSE 9.0 system (at home).
I took it to a default SuSE 9.1 system (at work), and the same script returned several syntax errors there.

It turned out that my code HAS CHANGED simply by having been taken to SuSE 9.1: all accented characters and the subsequent character have disappeared.
I think this is due to the fact that SuSE 9.1 is unicode-enabled by default.

However, it is a disaster, as it will destroy all of my scripts:

Lines like this are quite common in my scripts:
echo "Bet"

which will be changed to the following in SuSE 9.1:
echo "Bet

As you see, the same line lacks a quotation mark at the end in SuSE 9.1, and so the script will fail, or what is worse: the result is unpredictable, depending on the place where the change took place. In the most unfortunate case there are chances that a script working fine on SuSE 9.0 will do harm when run on SuSE 9.1.

I wonder what you think about this, and if there is a workaround?

I'm guessing that the language variables on the SUSE at are different than the language variables on your home machine.

Here's and answer which came from this thread:

http://www.linuxquestions.org/questi...hlight=unicode



( post #4)

I got this from a Faq .

-o nls={NAME}

NTFS stores all file and directory names in Unicode which can represent any character from any language. By default the Linux NTFS driver converts the names to ASCII which is OK for some people, but no good if your languages includes letters like or .

NLS (Native Language Support) controls how characters are displayed. You can choose either utf8 which, like Unicode, can represent all characters, or your own codepage, e.g. iso8859-1 (Western Europe), iso8859-2 (Central Europe), gb2312 (Simplified Chinese), iso8859-8 (Hebrew). Below are some example mount commands:

mount /dev/hda1 /mnt/windows -t ntfs -r -o nls=utf8
mount /dev/hda1 /mnt/windows -t ntfs -r -o nls=iso8859-2
mount /dev/hda1 /mnt/windows -t ntfs -r -o nls=gb2312

Ignore the ntfs parts.Try searching for NLS and you might find a better answer.
