The point I was trying to make is that with code like this:
cd /var/log && {
... do stuff ...
}
^
after the closed curly bracket above, if $? is _not_ 0 either the `cd'
command failed or some stuff inside the command list. But with:
! cd /var/log || {
... do stuff ...
}
^
at this point, if $? is _not_ 0 then you can be sure some stuff inside
the command list failed.
