I agree with you. ksh is exceptional. Smilie

My post isn't intended to suggest that bash (or dash or bourne sh) violate the standard -- I'm aware that POSIX allows a shell to execute each component of a pipeline in either the current environment or a subshell (ksh is compliant in this respect); the post is merely a response to methyl's rumination on the popularity of the idiom, identifying one popular resource which promotes it.

In my opinion, the ksh approach makes life a little easier. But, if I depend on it in a script, I always explicitly require ksh in the shebang.

Alister
