Thanks for the additional information. This is not broken in the upstream sources. It is also not broken in another distribution of the same version. Therefore I can only deduce that it must be a problem with a patch applied by your software distribution on top of the upstream sources. If you wish to pursue this further you will need to file a bug with your distribution. Or compile your own version from the GNU sources. The latest stable release of the GNU coreutils is available here: ftp://ftp.gnu.org/gnu/coreutils/coreutils-5.92.tar.gz (7.2MB) ftp://ftp.gnu.org/gnu/coreutils/coreutils-5.92.tar.bz2 (4.6MB) That is a very latest stable release. Please report any problems that you may find with it. > > echo sort -t "\0" > > sort -t \0 Looks good. I was a little concerned that the shell had done something interesting to the "\0" there.

The modified variant: > [EMAIL PROTECTED] tmp]$ sort -t \\0 Personally I find "\0" and '\0' easier to read than \\0.

I'll stick to TAB=$(echo -ne \\t) then. Thanks anyway for answering. Using 'echo -ne' is probably the *worst* of the alternatives. It is about as non-portable as it can get. I am cringing just looking at it. I strongly recommend using one of the alternatives that does not depend so heavily upon particular behavior of the shell. Best if it only depends upon standard features. Please use 'printf' at the least! Then there is a chance that it will work across POSIX shells.
