Useful Batch file commands

Batch files help user to execute series of commands in the batch file. We can execute large number of commands in one go using bat file.

Some useful batch commands:

@echo off – does not echo the text post the command and only displayes the execution result

@echo on the text post the command and only displays the execution result

Pause- the batch file execution is halted until further intervention of user by pressing keys.

CALL - calling one batch file from another batch file

cd -  Change directory

cls - clean the window

copy -copy files from source to destination

DIR - List of directory and files

ERASE - delete files

FC - Compares files
 
IF - Conditional statement

mkdir - Make a new directory/folder

move - move files or folder

ping - Check TCP/IP connection to a remote IP address

rmdir - remove folder/directory

SC - Managing services

set - manipulate environment variable 

taskkill - kills an active process

taslist - List active processes

REM - remark statement

Arguments %1….. – This is the first argument to be provided from the

 command prompt as parameter for the batch command.

Starting with batch files:

Let us take a simple example of using batch file to display Create a new file with extension as .bat. Suppose we need to compare two text files. The content of batch file for this will look like

@echo off

Fc %1 %2 /n>%3

Pause

To execute this bat file, we have to write in command prompt  as:

D:\new.bat d:\testsrc.txt d:\testdest.txt d:\testlog.txt

Renaming all/specific subfolders in a folder using vbscript FSO

In this post, how to rename all the subfolders in a folder using vbscript is explained

• Renaming all sub folders in a folder removing spaces from the file

call RemoveblankSpace_Subfolders("D:\TextTest")

 ''strbasefoldername - Folder Path in which file needs to be replaced
 Public Function RemoveblankSpace_Subfolders(strbasefoldername)
 On error resume next
 Dim objFSO
 Set objFSO = CreateObject("Scripting.FileSystemObject") 
    Dim objFolder 
    For Each objSubFolder In objFSO.GetFolder(strbasefoldername).SubFolders
     FlderName = objSubFolder.Name
  FlderName = replace(FlderName," ","")
  objSubFolder.Name = FlderName
    Next 
    Set objSubFolderFolder = Nothing 
    Set objFSO = Nothing 
End Function

• Rename specific subfolder in a folder using vbscript

call Rename_Subfolders("D:\TextTest","es","twist",false,"test")

'' strbasefoldername - Folder Path in which file needs to be replaced
'' strFindtext - text in the folder name that needs to be replaced
'' strReplaceText - new text to replace the existing test
'' boolAllFlders - boolean flag to indicate if all the subfolder needs to be renamed or

'' specific folders needs to be renamed
'' OnlyfoldersWithText - replace only folder with specific text. will consider only if

'' boolAllFlders =true
 Public Function Rename_Subfolders(strbasefoldername,strFindtext,strReplaceText,boolAllFlders,OnlyfoldersWithText)
 On error resume next
 Dim objFSO
 Set objFSO = CreateObject("Scripting.FileSystemObject") 
    Dim objFolder
    For Each objSubFolder In objFSO.GetFolder(strbasefoldername).SubFolders
 FlderName = objSubFolder.Name
  if boolAllFlders = false then
   if(instr(1,FlderName,OnlyfoldersWithText)>0) then
    FlderName = replace(FlderName,strFindtext,strReplaceText)
    objSubFolder.Name = FlderName
   End If
  else
    FlderName = replace(FlderName,strFindtext,strReplaceText)
    objSubFolder.Name = FlderName
  End If
    Next 
    Set objSubFolderFolder = Nothing 
    Set objFSO = Nothing 
End Function

UFT test information and failure reason from result.xml file

While running the UFT test in batch,we need to capture executed test information including testname, test execution status and reason for failure if any in the test execution. 
Below code in vbscript can be used to extract required information from results file (result.xml) in UFT and parsing the information in xml file using MSXML.DomDocument and Microsoft.XMLDOM

xmlFilePath = "c:\Results.xml"

Set xmlDoc = CreateObject("MSXML.DomDocument")
If xmlDoc.Load (xmlFilePath) Then
'Get the test name
 Set objNode = xmlDoc.GetElementsByTagName("DName")
 .TestName = objNode(0).Text
 Set objNode = xmlDoc.GetElementsByTagName("Summary")

 'Last Node with tagName "Summary" has details of Pass/Fail status
 Set Node = objNode(objNode.Length - 1)

 intStepsPassed = Node.getAttribute("passed")
 intStepsWarning = Node.getAttribute("warning")

 ''in case of failures get the testfailureReason
 If Cint(intStepsFailed) > 0 Then
  strFailureReason = getFailureReason(xmlFilePath)
 End if
 Set FSO = Nothing
 Set xmlDoc = Nothing
End If

Public function getFailureReason(strFileName)
 Set xmlDoc = CreateObject("Microsoft.XMLDOM")
 xmlDoc.async = False
 strErrorMsg = ""
 booleanxmlParse = xmlDoc.load(strFileName)
 if(booleanxmlParse) then
  xmlDoc.setProperty "SelectionLanguage", "XPath"
  set xmlDoc_node = xmlDoc.selectNodes("//Step//NodeArgs[@status='failed']")
  for each node in xmlDoc_node
   strNode = node.parentNode.getattribute("rID")
   set TCNode = xmlDoc.selectSingleNode("//Step[@rID='" + strNode + "']/Details")
   strErrorMsg=strErrorMsg & TCNode.text
  Next
 End If
 getFailureReason = strErrorMsg 
End Function
