Bash should do the CR-LF conversion for both forms of command output expansion: `cmd` and $(cmd). Sh should do the conversion for the backticks form. It's interesting that cat was placed in the line-oriented textutils package rather than something like fileutils or shellutils. But then again so was od and the checksum utilities like sum and md5sum. What cat's -B option for? Since it's not in the FSF documentation, I thought it was a cygwin addition that forced cat to *not* do the LF to CR-LF output translation. To me it implies that cat is reading and writing in textmode, not binmode. Since it will take a while to fix all the shells, should a --text flag be added to cat? I know it's ugly, but it saves people the trouble of having to find a B20.1 version of cat. - Erik -- Want to unsubscribe from this list?
