Question

这是我生成图表并将它们组合起来的脚本。问题是当我给出输入并在终端中运行文件时，它在转储文件中显示为null。我认为它也没有执行mysql命令。如果我在命令本身给出输入datetime1，datetime2和moteid，Mysql命令工作正常。我无法找到我在mysql查询中出错的地方

datetime1=$1

DATETIME2 = $ 16 moteid = $ 3'/ P>

RUN SUCCESSFUL (total time: 154ms)

如果我给这个mysql查询而不是那个，它的工作正常

mysql -u root -e "SELECT (b.l2framessent - a.l2framessent) AS netl2framessent,(b.Frames_Drop-a.Frames_Drop) AS netframesdrop,(b.ETX - a.ETX) AS netetx,CONVERT(endOfInterval*500, DATETIME) endOfInterval FROM (SELECT datetime DIV 500 startOfInterval,l2framessent,Frames_Drop,ETX FROM Statistics3,(SELECT MIN(datetime) mindate FROM Statistics3 WHERE ipaddress='moteid5' AND datetime BETWEEN '2012-09-25 15:45:00' AND '2012-09-25 18:45:00' GROUP BY datetime DIV 500) b WHERE ipaddress='moteid5' AND datetime = mindate) a, (SELECT datetime DIV 500 endOfInterval, l2framessent,Frames_Drop,ETX FROM Statistics3, (SELECT MIN(datetime) mindate FROM Statistics3 WHERE ipaddress = 'moteid5' AND datetime BETWEEN '2012-09-25 15:45:00' AND '2012-09-25 18:45:00' GROUP BY datetime DIV 500) b WHERE ipaddress = 'moteid5'AND datetime = mindate) b WHERE endOfInterval = startOfInterval+ 1 ;" >> dump

Answer 1

命令：

sed '1d'

没有给出输入文件，所以它从标准输入读取。所以它等着你输入一些东西。我怀疑你的意思是将mysql的输出传递给它，所以它应该是：

mysql -u root -e "SELECT ..." | sed 1d >> filename

Answer 2

而不是5在mote，我必须给moteid5.Its现在没有显示任何错误

由于mysql查询，没有在shell脚本中输出
