" if you save the ksh source in listing 1 , below , as ex1 . ksh and then run it , you ll see a " countdown " - " ten , nine , eight , etc . " - display , then the result of the ksh subprocess : " all done . " in practice , you might use something like this for a long - running chemical calculation or database retrieval : launch the operation as a subprocess , but keep users informed about what s going on or how much time is left before completion
此外，至少自1988年以来，基本上已经在所有unix主机上实现了简单的并发编程，在1988年这一年ksh对其“协同进程（ co - process ） ”进行了标准化。如果您将下面清单1中的ksh源代码保存为ex1 . ksh ，然后运行它，您会看到“倒计时”显示： “十、九、八，等等” ，然后看到ksh子进程的结果： “ all done ” 。实际运用中，您可能会对长期运行的化学计算或数据库检索使用类似这样的操作：启动操作作为子进程，但是让用户始终知道操作的进展或完成之前还剩多少时间。
