With this set of patches perl built OK with zsh linked to sh and
passed all tests, the process including & -d, shell escapes, etc. I
couldn't rewire /bin/sh, but most shell scripts during the build are
called with an explicit `sh', so this is quite a good test.
I'm planning on including a clearer summary of compatiblity in the
appropriate section of the FAQ, B1; here is a preview.
As a summary of the status:
i) because of all the options it is not safe to assume a general
zsh run by a user will behave as if sh or ksh compatible;
ii) invoking zsh as sh or ksh (including if either is a symbolic
link to zsh) sets appropriate options and improves
iii) from version 3.0 onward the degree of compatibility with sh
under these circumstances is very high: zsh can now be used
with GNU configure or perl's Configure, for example;
iv) the degree of compatibility with ksh is also high, but a few
things are missing: for example the more sophisticated
pattern-matching expressions are different --- see the detailed
v) also from 3.0, the command `emulate' is available: `emulate
ksh' and `emulate sh' set various options as well as changing the
effect of single-letter option flags as if the shell had been
invoked with the appropriate name. Including the commands
`emulate sh; setopt localoptions' in a shell function will
turn on sh emulation for that function only.
