  17. What s more, simple concurrent programming has been available on essentially all unix hosts since at least 1988, which is when ksh standardized its " co - processes. " 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年以來,基本上已經在所有unix主機上實現了簡單的並發編程,在1988年這一年ksh對其「協同進程( co - process ) 」進行了標準化。如果您將下面清單1中的ksh源代碼保存為ex1 . ksh ,然後運行它,您會看到「倒計時」顯示: 「十、九、八,等等」 ,然後看到ksh子進程的結果: 「 all done 」 。實際運用中,您可能會對長期運行的化學計算或數據庫檢索使用類似這樣的操作:啟動操作作為子進程,但是讓用戶始終知道操作的進展或完成之前還剩多少時間。
