   8  * execunix.c - execute a shell script on UNIX
   9  *
  10  * If $(JAMSHELL) is defined, uses that to formulate execvp().
  11  * The default is:
  12  *
  13  *  /bin/sh -c %
  14  *
  15  * Each word must be an individual element in a jam variable value.
  16  *
  17  * In $(JAMSHELL), % expands to the command string and ! expands to
  18  * the slot number (starting at 1) for multiprocess (-j) invocations.
  19  * If $(JAMSHELL) doesn't include a %, it is tacked on as the last
  20  * argument.
  21  *
  22  * Don't just set JAMSHELL to /bin/sh - it won't work!
  23  *
  24  * External routines:
  25  *  execcmd() - launch an async command execution
  26  *  execwait() - wait and drive at most one execution completion
  27  *
  28  * Internal routines:
  29  *  onintr() - bump intr to note command interruption
  30  *
  31  * 04/08/94 (seiwald) - Coherent/386 support added.
  32  * 05/04/94 (seiwald) - async multiprocess interface
  33  * 01/22/95 (seiwald) - $(JAMSHELL) support
  34  * 01/20/00 (seiwald) - Upgraded from K&R to ANSI C
