Implement the P1003.2 `command' builtin command, which is used to suppress shell function and alias lookup. The -p option has been implemented, the UPE -v and -V options have not. The old `command' command has been renamed to `builtin'. 2002-07-21 06:49:14 +00:00			`bltincmd builtin`

Make test(1) a builtin command of our sh(1) for efficiency. The binary size increase is 3,784 bytes (about 0.6%). I don't drop the printf builtin while I'm here because some /etc/rc.* scripts seem to use it before mounting /usr where printf(1) resides.

Remove the printf builtin command from sh(1), which command is not used so often that it's worth keeping it as a builtin. Now that all the printf invocations from within the system startup scripts, we can safely remove it. Urged by: sheldonh :) No MFC is planned so far because it may break compatibility and violate POLA. 2001-11-20 18:33:59 +00:00			`#printfcmd printf`

Add the times builtin. It reports the user and system time for the shell itself and its children. Instead of calling times() (as implied by POSIX) this implementation directly calls getrusage() to get the times because this is more convenient. 2005-12-04 18:44:21 +00:00			`timescmd times`

Add a `bind' builtin command, which is simply a wrapper around libedit's builtin command of the same name. This allows the key bindings for the shell's line editor to be changed. MFC after: 2 weeks 2002-07-23 11:50:53 +00:00			`bindcmd bind`
