Hi!
Simple test case:
----8<----------------------
#!/bin/sh
foo()
{
echo "\$?=3D$? \$1=3D$1"
}
false
foo $?
----8<----------------------
% sh foo.sh
$?=3D0 $1=3D1
% zsh foo.sh
$?=3D1 $1=3D1
% bash foo.sh
$?=3D1 $1=3D1
As you can see, the value of $? is =AB lost =BB when FreeBSD sh enters a
function. Is this supposed to behave this way?
Thanks,
Romain
