See more: batch script DOS
Hi,
 
I have to write a batch script for comparing two files.
The filenames should be like -- HP_OTT_todaydate.txt and HP_OTT_yesterdaydate.txt
 
HT_OTT is fixed part in both filenames.
 
I want to get today's date and yesterday's date and suffix these date to the fixed part of filename.
 
I am using FC command and It should be like this,
 
FC C:\HP_OTT_TodaysDate.txt   C:\HP_OTT_YesterdayDate.txt
 
I have coded something like this in my batch file,
 

FC C:\HP_OTT.txt   C:\HP_OTT%date:~-10,2%%date:~-7,2%%date:~-4,4%.txt
 

This part
C:\HP_OTT%date:~-10,2%%date:~-7,2%%date:~-4,4%.txt
is suffixing today's date to fixed filename part of first file and giving me file name as HT_OTT04052012 and that's what I am expecting.
 
But I am getting difficulty for suffixing yesterday's date to the second filename.
 
I have been stucked on this issue since 3 days; any alternative approach would be great helpful.

P.S. - I am using Windows 7 Pro 64 bit.

Solution 1

I am able to solve problem using powershell,
 
$yesterday = Get-Date -UFormat %d%m%Y -Date (Get-Date).adddays(-1)
$today=Get-Date -UFormat %d%m%Y
 
$strReference = Get-Content C:\batchtest\HP_OTT$today.txt
$strDifference = Get-Content  C:\batchtest\HP_OTT$yesterday.txt
 Compare-Object $strReference $strDifference >C:\batchtest\result.txt
