Question

我正在编写一个后期会话shell脚本，我必须计算一个平面文件行数的目标，如果计数大于500，则发送通知相同的邮件。但是剧本中有一些错误。

DIR="/data/research_dev/inbfiles"
cd /data/research_dev/inbfiles
if [ "$(wc -l ff_invoicepreviewqueue1.csv)" > 500 ]; then
echo "Hi," > InvoicePreview.dat
echo " The row count of InvoicePreviewQueue is:   " >> InvoicePreview.dat
#wc -l ff_invoicepreviewqueue1.csv >> InvoicePreview.dat
echo "                  " >> InvoicePreview.dat
echo "            " >> InvoicePreview.dat
echo "Thanks and Regards," >> InvoicePreview.dat
echo "BI Support team." >> InvoicePreview.dat
mailx -s "Alert!! Count is out of limits!! " "correia.blossom@rexelholdingsusa.com" < InvoicePreview.dat
rm -f InvoicePreview.dat.dat
#

请帮我找出错误

Answer 1

命令wc -l ff_invoicepreviewqueue1.csv通常会返回带有文件名的计数，例如499 ff_invoicepreviewqueue1.csv。因此，您无法将其与500进行比较。您可能会执行cat ff_invoicepreviewqueue1.csv|wc -l之类的操作，而这只会返回计数。

另外，运算符大于“-gt”，“＆gt;”可能不会工作。所以要重写你的if语句，它将是：

if [ "$(cat ff_invoicepreviewqueue1.csv|wc -l)" -gt 500 ]; then

    # send mail

fi

请记住使用fi。

关闭if条件

谢谢你的帮助.. 我从sql server源加载了目标flatfile，然后在赋值任务中我分配了带有源成功行的工作流变量，在决策任务中，如果行大于500我称为script1，如果行少，我称为script2

 Rows="$(cat /data/research_dev/inbfiles/ff_invoicepreviewqueue.txt|wc -l)"
 echo "Hi," > InvoicePreview.dat
 echo " The row count of InvoicePreviewQueue is:   " >> InvoicePreview.dat
 echo $Rows" Rows">> InvoicePreview.dat
 echo " Please re run the process to correct the count   " >> InvoicePreview.dat
 echo "   " >> InvoicePreview.dat
 echo "                 " >> InvoicePreview.dat
 echo "Thanks and Regards," >> InvoicePreview.dat
 echo "BI Support team." >> InvoicePreview.dat
 mailx -s "Alert!! The count of InvoicePreviewQueue is "$Rows"!! " "correia.blossom@rexelholdingsusa.com" < InvoicePreview.dat
 rm -f InvoicePreview.dat.dat
  #

还有一个脚本，如果计数小于500则执行并发送邮件。谢谢大家的帮助！
