Merge of 4.4-Lite2 sh source, plus some gcc -Wall cleaning. This is a merge of parallel duplicate work by Steve Price and myself. :-] There are some changes to the build that are my fault... mkinit.c was trying (poorly) to duplicate some of the work that make(1) is designed to do. The Makefile hackery is my fault too, the depend list was incomplete because of some explicit OBJS+= entries, so mkdep wasn't picking up their source file #includes. This closes a pile of /bin/sh PR's, but not all of them.. Submitted by: Steve Price <steve@bonsai.hiwaay.net>, peter

PROG= sh
Install /bin/sh safely. This allows a shell script to be used to strip binaries by specifying it in the STRIPBIN environment variable honoured by install(1). MFC after: 3 days

sh: Import arithmetic expression code from dash. New features: * proper lazy evaluation of || and && * ?: ternary operator * executable is considerably smaller (8K on i386) because lex and yacc are no longer used Differences from dash: * arith_t instead of intmax_t * imaxdiv() not used * unset or null variables default to 0 * let/exp builtin (undocumented, will probably be removed later) Obtained from: dash

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.

mystring.c options.c output.c parser.c printf.c redir.c show.c \
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.

Improve shell documentation: * Consistently misspell built-in as builtin. * Add a builtin(1) manpage and create builtin(1) MLINKS for all shell builtin commands for which no standalone utility exists. These MLINKS replace those that were created for csh(1). * Add appropriate xrefs for builtin(1) to the csh(1) and sh(1) manpages, as well as to the manpages of standalone utilities which are supported as shell builtin commands in at least one of the shells. In such manpages, explain that similar functionality may be provided as a shell builtin command. * Improve sh(1)'s description of the cd builtin command. Csh(1) already describes it adequately. Replace the cd(1) manpage with a builtin(1) MLINKS link. * Clean up some mdoc problems: use Xr instead of literal "foo(n)"; use Ic instead of Xr for shell builtin commands. * Undo English contractions.
