关于bc的问题

[枫叶饭团]

我现在有一个600多行的脚本，因为涉及一些敏感信息，所以我只能po一部分了。。
现在主逻辑

代码： 全选

while read  ppl
do
	part_judge_alarm "${ppl}" &
done < ${ldir}/mon_part_info.txt.${tstamp}

在part_judege_alarm函数里用到了大量的bc进行浮点数大小对比，比如

代码： 全选

[ `echo "${ninout}>${inout}"|bc` -eq 1 ]

但是，一直报错(standard_in) 1: parse error。。。。。。。。。。而且出现得莫名其妙

代码： 全选

++{257:part_judge_alarm}bc
+{391:part_judge_alarm}'[' 0 -eq 1 ']'
++{286:part_judge_alarm}bc
++{414:part_judge_alarm}echo '0.0000>0.35'
+{245:part_judge_alarm}pu=0
(standard_in) 1: parse error
+{245:part_judge_alarm}pu=0
++{414:part_judge_alarm}bc
+{257:part_judge_alarm}ydpu=
++{246:part_judge_alarm}echo '172.22.108.160|/data|860544|2294|117899264|384|0.2665|1.0000|0.00|-0.0007|0.0000'
+{258:part_judge_alarm}'[' -z '' ']'
--
++{257:part_judge_alarm}bc
++{256:part_judge_alarm}head -1
++{245:part_judge_alarm}awk '-F|' '{print $7}'
++{454:part_judge_alarm}bc
++{250:part_judge_alarm}grep 172.27.34.90 /usr/local/app/log.wsd.com/josephfu/alarmlog/ydmon_part_info.txt.201304061750
(standard_in) 1: parse error
+{257:part_judge_alarm}ydpu=
+{258:part_judge_alarm}'[' -z '' ']'
+{258:part_judge_alarm}ydpu=1
++{245:part_judge_alarm}awk '{printf("%d",$1)}'
+{246:part_judge_alarm}iu=1

我只是想问问，有人遇见过相同的问题么。。。。实在没办法提供太多的信息，不好意思。。。

看来是企鹅

找到原因了，我操。。。
就因为那个&产生的并行运算，导致日志太乱了。
事实上是因为这个脚本对符点数进行
类似于

代码： 全选

a=`echo "${a}/1"|bc`

的操作，直接报错，这是为什么啊
