51 * Shell Specifications:
53 * Some special stuff goes on if a shell doesn't have error control. In such
54 * a case, errCheck becomes a printf template for echoing the command,
55 * should echoing be on and ignErr becomes another printf template for
56 * executing the command while ignoring the return status. If either of these
57 * strings is empty when hasErrCtl is FALSE, the command will be executed
58 * anyway as is and if it causes an error, so be it.
