/*
* execunix.c - execute a shell script on UNIX
*
* If $(JAMSHELL) is defined, uses that to formulate execvp().
* The default is:
*
* /bin/sh -c %
*
* Each word must be an individual element in a jam variable value.
*
* In $(JAMSHELL), % expands to the command string and ! expands to
* the slot number (starting at 1) for multiprocess (-j) invocations.
* If $(JAMSHELL) doesn't include a %, it is tacked on as the last
* argument.
*
* Don't just set JAMSHELL to /bin/sh - it won't work!
*
* External routines:
* execcmd() - launch an async command execution
* execwait() - wait and drive at most one execution completion
*
* Internal routines:
* onintr() - bump intr to note command interruption
*
* 04/08/94 (seiwald) - Coherent/386 support added.
* 05/04/94 (seiwald) - async multiprocess interface
* 01/22/95 (seiwald) - $(JAMSHELL) support
* 01/20/00 (seiwald) - Upgraded from K&R to ANSI C
* 05/06/05 (seiwald) - new execmax() to return max command line len.
