重试连接超时bash命令 [英] Retry a Bash command with timeout

问题描述

如何直至其状态是否正常，直到达到超时重试bash命令？

我的最佳拍摄（我要找的东西简单）：

  NEXT_WAIT_TIME = 0
COMMAND_STATUS = 1
直到[$ COMMAND_STATUS -eq 0 || $ NEXT_WAIT_TIME -eq 4]。做
  命令
  COMMAND_STATUS = $？
  睡眠$ NEXT_WAIT_TIME
  让NEXT_WAIT_TIME = NEXT_WAIT_TIME + 1
DONE
 

解决方案

您可以简化事情有点通过将命令就在测试和做递增有点不同。不然，该脚本看起来不错：

  NEXT_WAIT_TIME = 0
直到命令|| [$ NEXT_WAIT_TIME -eq 4〕;做
   睡眠$（（NEXT_WAIT_TIME ++））
DONE
 

How to retry a bash command until its status is ok or until a timeout is reached?

My best shot (I'm looking for something simpler):

NEXT_WAIT_TIME=0
COMMAND_STATUS=1
until [ $COMMAND_STATUS -eq 0 || $NEXT_WAIT_TIME -eq 4 ]; do
  command
  COMMAND_STATUS=$?
  sleep $NEXT_WAIT_TIME
  let NEXT_WAIT_TIME=NEXT_WAIT_TIME+1
done

解决方案

You can simplify things a bit by putting command right in the test and doing increments a bit differently. Otherwise the script looks fine:

NEXT_WAIT_TIME=0
until command || [ $NEXT_WAIT_TIME -eq 4 ]; do
   sleep $(( NEXT_WAIT_TIME++ ))
done
