There is one more solution which I have seen in Solaris. Many
commands are environment-sensitive.
For example, we can have the CMD_BEHAVIOR environment variable, which
can have values "POSIX" (or "POSIX:1812.321"), "BSD", "LINUX",
"SOLARIS", ...
So we can use these conditions:
if $CMD_BEHAVIOR is unset or $CMD_BEHAVIOR == "" then CMD_BEHAVIOR=POSIX
if $CMD_BEHAVIOR == POSIX then f_listdot = 0
if $CMD_BEHAVIOR == BSD and UID == 0 then f_listdot = 1
In this case I can change a command behavior in my shell scripts, and
my scripts can be OS-independent.
How would that be OS-independent if only implemented on Solaris and its
derivatives? ;) That's like saying JAVA is a highly portable language :P
he means OS-independent scripts (scripts that a user writes for his own
purpose). the proposed approach makes it more possible for a user to
write such a script indeed.
though, not without limitations while only Solaris and Dragonfly
implement it :)
and may be the most important point is:
this approach makes migration to Dragonfly easier.
