I was investigating my options for controlling the new built-ins
with ksh-20120929, and I happened to notice some garbled output for the
-n option of the builtin command:
$ builtin --?
Usage: builtin [ options ] [pathname ...]
OPTIONS
-d Deletes each of the specified built-ins. Special built-ins
cannot be deleted.
-f lib On systems with dynamic linking, lib names a shared
library
to load and search for built-ins. Libraries are
searched for
in ../lib/ksh and ../lib on $PATH and in system dependent
library directories. The system dependent shared library
prefix and/or suffix may be omitted. Once a library is
loaded, its symbols become available for the current and
subsequent invocations of builtin. Multiple libraries
can be
specified with separate invocations of builtin.
Libraries are
searched in the reverse order in which they are specified.
-n Disable each of the specified built-ins. Special built-ins
cannot be disabled. If no built-ns are specifed,
display all
disabled built-ins.][l?List the library base name,
plugin YYYYMMDD version stamp, and full path for -flib on one line on
the standard output.
-p Causes the output to be in a form of builtin commands that
can be used as input to the shell to recreate the
current set
of builtins.
-s Display only the special built-ins.
A quick check of src/cmd/ksh93/data/builtins.c revealed an extra square
bracket at the end of the -n option. Removing the extra square bracket
not only fixed the garbled output, but it also made the -l option
functional. I've attached builtin.c.diff to apply the fix.
