如您所见，它针对以下行返回空值:
23:59:05 - - -1439 min outer: 550 scs01: 1 scs02: 5 scs03: 6 scs04: 5 scs05: 13 scs07: 2 scs08: 11 scs09: 7 scs10: 6 scs11: 3 scs12: 12 scs13: 6 scs14: 4 scs15: 6 scs17: 6 scs18: 7 scs19: 6 scs20: 8
这应该类似于上面和下面的行。 ([时间] - [时间] - [持续时间] 等)
这反过来又影响时间计算(负数)
我需要在 scsoutergreen 调用周围放置一些东西以阻止它返回空值。我尝试过以下方法:
if [ -n "scsoutergreen[a]" ]; then "23:55:99" fi
但这会在 if、] 和 then 上返回语法错误。
有什么想法吗？
提前致谢
最佳答案
我设法让它工作。
我做了以下事情:

我对原始版本所做的更改是我将脚本下半部分中 t 变量的设置修改为:
t = (substr(scsoutergreen[a],1,2)-substr(scsouterred[a],1,2))*60+(substr(scsoutergreen[a],4,2)-substr(scsouterred[a],4,2))
至以下内容:
if (((substr(scsoutergreen[a],1,2)-substr(scsouterred[a],1,2))*60)<=0&&(substr(scsoutergreen[a],4,2)-substr(scsouterred[a],4,2))<=0) {t = 0} #start of t = if
else if (((substr(scsoutergreen[a],1,2)-substr(scsouterred[a],1,2))*60)<= 0) {t = (0+(substr(scsoutergreen[a],4,2)-substr(scsouterred[a],4,2)))}
else if ((substr(scsoutergreen[a],4,2)-substr(scsouterred[a],4,2))<= 0) {t = (((substr(scsoutergreen[a],1,2)-substr(scsouterred[a],1,2))*60)+0)}
else {t = ((substr(scsoutergreen[a],1,2)-substr(scsouterred[a],1,2))*60+(substr(scsoutergreen[a],4,2)-substr(scsouterred[a],4,2)))}
这解决了空时间问题，如果时间计算结果为 <= 0，则返回 0；如果不是，则返回实际计算结果。
关于linux - sh/awk(部分)脚本返回空值但希望它返回一个值，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34370775/
