并行调用多个功能在ksh脚本中间歇性地工作

Question

并行调用多个功能在Bash脚本中间歇性地工作。

我正在尝试在bash脚本中并行调用多个函数。 所有功能都包含相同的代码和逻辑，但是功能call_bpa和call_inv间歇地工作。 出现错误[：函数call_bpa或call_inv中期望的参数。

流量：

提交CPA计划。 如果CPA计划已完成， 并行调用函数call_po，call_bpa和call_inv。 如果call_po和call_inv完成，则  调用函数call_chk 万一; 万一; 检查所有功能是否完成，然后

打印完成。

在任何类似bourne的外壳上...

cpa_program() { echo cpa_program; }
call_po()     { echo call_po;     }
call_bpa()    { echo call_bpa;    }
call_inv()    { echo call_inv;    }
call_chk()    { echo call_chk;    }

cpa_program

{
    call_po &
    call_inv &
    wait
    call_chk
} &
call_bpa &
wait
echo completed

您可以在上面的任何函数中放置sleep 1;，以查看并行性如何工作。

1. 您可以在任何地方摆脱&来序列化所有内容。先尝试一下，然后在完全执行串行执行后并行化。
2. 简化代码并逐步调试。调试时，我在调试之前在命令前使用echo，以查看在完全启用脚本之前在每一行上要调用什么。
3. 如果要并行执行，请确保函数调用位于单独的行上，并且&位于编写的每一行的末尾。单行执行call_po & call_inv & call_foo是不正确的。
4. 对wait的调用很重要-它们会阻止，直到并行执行步骤完成。
