ksh，达到循环最大值时执行操作 [英] ksh, perform action when reaching loop maximal value

问题描述

我希望编写一个小的korn shell脚本，进行5个测试(每次测试之前要等待一段时间)，然后，如果它们全部失败，则执行一个操作.

I am looking to write a small korn shell script doing 5 tests (by waiting some time before each one) and then, if they all fail, performing an action.

我当时正在做类似的事情:

I was looking at doing something like :

    for i in {1..5}
    do
       "doMyTest"             #it fills a variables "status" (but can unfortunately fails)
       if [ "$status" ]; then #if status is filled then we can leave the loop
          break
       fi
       sleep 3                #else wait some time before doing another try
    done

    if [ -z "$status" ]; then
       exit 1
    fi

... then the rest of my program

您是否知道我该如何更好地做到这一点? 听起来有点多余...

Do you have any idea how could I do this in a better way ? It sounds a bit redundant ...

非常感谢您.

推荐答案

您只想在所有测试失败时看到失败吗? 如果一个测试成功后可以跳过其他测试，则可以使用

You only want to see a failure when all tests fail? When you can skip the other tests when one test succeeds, you can use

test1 || sleep 3 && \
   test2 || sleep 3 && \
   test3 || sleep 3 && \
   test4 || sleep 3 && \
   test5 || exit 1
