.Sh DESCRIPTION
|
||||
.Nm
|
||||
is a command interpreter intended exclusive for running legacy
|
||||
shell scripts.
|
||||
It is built on
|
||||
.Nm mksh ;
|
||||
refer to its manual page for details on the scripting language.
|
||||
.Sh LEGACY MODE
|
||||
.Nm
|
||||
has the following differences from
|
||||
.Nm mksh :
|
||||
.Bl -bullet
|
||||
.It
|
||||
.Nm
|
||||
is not suitable for use as
|
||||
.Pa /bin/sh .
|
||||
.It
|
||||
There is no explicit support for interactive use,
|
||||
nor any command line editing code.
|
||||
Hence,
|
||||
.Nm
|
||||
is not suitable as a user's login shell, either; use
|
||||
.Nm mksh
|
||||
instead.
|
||||
.It
|
||||
The
|
||||
.Ev KSH_VERSION
|
||||
string identifies
|
||||
.Nm
|
||||
as
|
||||
.Dq LEGACY KSH
|
||||
instead of
|
||||
.Dq MIRBSD KSH .
|
||||
.It
|
||||
Some
|
||||
.Nm mksh
|
||||
specific extensions are missing; specifically, the
|
||||
.Fl T
|
||||
command-line option.
|
||||
.It
|
||||
Some extensions from other shells, such as
|
||||
.Tn GNU
|
||||
.Nm bash ,
|
||||
which
|
||||
.Nm mksh
|
||||
provides, are missing, for increased compatibility with legacy scripts.
|
||||
.It
|
||||
.Nm
|
||||
always uses traditional mode for constructs like:
|
||||
.Bd -literal -offset indent
|
||||
$ set -- $(getopt ab:c "$@")
|
||||
$ echo $?
|
||||
.Ed
|
||||
.Pp
|
||||
POSIX mandates this to show 0, but traditional mode
|
||||
passes through the errorlevel from the
|
||||
.Xr getopt 1
|
||||
command.
|
||||
.It
|
||||
.Nm lksh ,
|
||||
unlike
|
||||
.At
|
||||
.Nm ksh ,
|
||||
does not keep file descriptors \*(Gt 2 private.
|
||||
.It
|
||||
.Nm
|
||||
parses leading-zero numbers as octal (base 8).
|
||||
.It
|
||||
Integers use the host C environment's
|
||||
.Vt long
|
||||
type, not
|
||||
.Vt int32_t .
|
||||
Unsigned arithmetic is done using
|
||||
.Vt unsigned long ,
|
||||
not
|
||||
.Vt uint32_t .
|
||||
Neither value limits nor wraparound is guaranteed.
|
||||
Dividing the largest negative number by \-1 is Undefined Behaviour
|
||||
.Po
|
||||
but might work on 32-bit and 64-bit
|
||||
.Vt long
|
||||
types
|
||||
.Pc .
|
||||
.It
|
||||
.Nm
|
||||
only offers the traditional ten file descriptors to scripts.

.Sh CAVEATS
|
||||
.Nm
|
||||
tries to make a cross between a legacy bourne/posix compatibl-ish
|
||||
shell and a legacy pdksh-alike but
|
||||
.Dq legacy
|
||||
is not exactly specified.
|
||||
Parsing numbers with leading zero digits or
|
||||
.Dq 0x
|
||||
is relatively recent in all
|
||||
.Nm pdksh
|
||||
derivates, but supported here for completeness.
|
||||
It might make sense to make this a run-time option, but
|
||||
that might also be overkill.
|
||||
.Pp
|
||||
The
|
||||
.Ic set
|
||||
built-in command does not have all options one would expect
|
||||
from a full-blown
|
||||
.Nm mksh
|
||||
or
|
||||
.Nm pdksh .
|
||||
.Pp

||||
Talk to the
|
||||

development team using the mailing list at

|
||||
if you need any further quirks or assistance,
|
||||
and consider migrating your legacy scripts to work with
|
||||
.Nm mksh
|
||||
instead of requiring
|
||||
.Nm .
