值对于基数太大(错误令牌为"09") [英] Value too great for base (error token is "09")

问题描述

运行我的bash脚本的这一部分时出现错误

When running this part of my bash script am getting an error

脚本

value=0
for (( t=0; t <= 4; t++ ))
do
d1=${filedates[$t]}
d2=${filedates[$t+1]}
((diff_sec=d2-d1))
SEC=$diff_sec
compare=$((${SEC}/(60*60*24)))
value=$((value+compare))
done

输出

jad.sh: line 28: ((: 10#2014-01-09: value too great for base (error token is "09")
jad.sh: line 30: /(60*60*24): syntax error: operand expected (error token is "/(60*60*24)")

d1和d2是采用2014-01-09和2014-01-10格式的日期

d1 and d2 are dates in that form 2014-01-09 and 2014-01-10

请问有什么解决方法吗?

Any solution please?

推荐答案

在变量的前面加上字符串"10#".这迫使bash将它们视为十进制，即使前导零通常会使它们变为八进制.

Prepend the string "10#" to the front of your variables. That forces bash to treat them as decimal, even though the leading zero would normally make them octal.
