\0nnn

be 0 to 3 octal digits)

enable [-pnds] [-a] [-f filename] [name...]
enable
Enable and disable builtin shell commands. This allows you to use a
disk command which has the same name as a shell builtin without
specifying a full pathname. If
-n
is used, the
NAME
s become disabled;
otherwise
NAME
s are enabled. For example, to use the
test
found in
$PATH
instead of the shell builtin version, type
enable -n test
.
On systems supporting dynamic loading, the
-f
option may be used
to load new builtins from the shared object
FILENAME
. The
-d
option
will delete a builtin previously loaded with
-f
. If no non-option names
are given, or the
-p
option is supplied, a list of builtins is printed. The
-a
option means to print every builtin with an indication of whether
or not it is enabled. The
-s
option restricts the output to the POSIX.2
`special' builtins. The
-n
option displays a list of all disabled builtins.
eval [ARG ...]
eval
Read
ARG
s as input to the shell and execute the resulting command(s).
exec [-cl] [-a name] file [redirection ...]
exec
Exec
FILE
, replacing this shell with the specified program. If
FILE
is not specified, the redirections take effect in this shell. If the first ar-
gument is
-l
, then place a dash in the zeroth arg passed to
FILE
, as
login does. If the
-c
option is supplied, FILE is executed with a null
environment. The
-a
option means to make set argv[0] of the executed
