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'.

sh: Remove the "exp" builtin. The "exp" builtin is undocumented, non-standard and not very useful. If exp's return value is not used, something like VAR=$(exp EXPRESSION) is equivalent to VAR=$((EXPRESSION)) except that errors in the expression are fatal and quoting special characters is not needed in the latter case. If exp's return value is used, something like if exp EXPRESSION >/dev/null can be replaced by if [ $((EXPRESSION)) -ne 0 ] with similar differences. The exp-run showed that "let" is close enough to bash's and ksh's builtin that removing it would break a few ports. Therefore, "let" remains in 9.x. PR: bin/104432 Exp-run done by: pav (with some other sh(1) changes)

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. Reviewed by: arch (sheldonh) Inspired by: NetBSD, ksh Clued by: ume (on how the printf builtin is used)

sh: Add kill builtin. This allows specifying a %job (which is equivalent to the corresponding process group). Additionally, it improves reliability of kill from sh in high-load situations and ensures "kill" finds the correct utility regardless of PATH, as required by POSIX (unless the undocumented %builtin mechanism is used). Side effect: fatal errors (any error other than kill(2) failure) now return exit status 2 instead of 1. (This is consistent with other sh builtins, but not in NetBSD.) Code size increases about 1K on i386. Obtained from: NetBSD

sh: Add printf builtin. This was removed in 2001 but I think it is appropriate to add it back: * I do not want to encourage people to write fragile and non-portable echo commands by making printf much slower than echo. * Recent versions of Autoconf use it a lot. * Almost no software still wants to support systems that do not have printf(1) at all. * In many other shells printf is already a builtin. Side effect: printf is now always the builtin version (which behaves identically to /usr/bin/printf) and cannot be overridden via PATH (except via the undocumented %builtin mechanism). Code size increases about 5K on i386. Embedded folks might want to replace /usr/bin/printf with a hard link to /usr/bin/alias.
