Re: Zsh as /bin/sh on Linux?

In your mail, you said:

The problem with zsh as a substitute for /bin/sh are minor incompatibilities
with sh, which (although they can even be features) can force scripts to
fail. Examples could be shwordsplit (although it might be turned on when zsh
is invoked as sh, I don't know), or subshells and pipelines (e.g. in while
constructs).

Sh has many dark sides which are often heavily used, thus it is better to
leave the original sh's, or (in Linux's case) bash, which is specialized for
imitating sh's glitches.
