Using <cfexecute/> with Windows Batch Files

ColdFusion , Gotchas , Windows Add comments

Recently I wrote some batch files to complement some scheduled tasks I was developing to help with automating some processes that were being carried out manually by system administrators on applications deployed in a Microsoft Windows environment.

In doing so I came across a number of minor issues that I had to figure out, so I thought I'd share them here for anyone else who's ever required to do anything similar.

I was calling the batch file using the <cfexecute /> tag and passing some arguments to keep the script cohesive enough that its functionality could be used on other servers.

The code final code I used is below but I have discussed the important parts that I had left out.

        args = [1];
        args[1] = "argument1Value";
        args[2] = "argument2Value";
        args[3] = "argument3Value";
    <cfexecute variable="batchScriptOutput" 
         SCRIPT OUTPUT:<br />#batchScriptOutput#<br />
         ERRORS:<br />#batchScriptError#<br />
	    <cfrethrow />        

The issues I had were that:

  • I wanted to pass argument values that had spaces in them
  • I wanted to see the output generated by the batch file

Neither of this seemed possible without formatting the code as I have above.  If a "timeout" value wasn't set, I didn't get the output returned and it just seemed simpler to pass the arguments as an array.

If anyone has had any similar experiences or better methods of implementation, I would like to hear your thoughts.

    Another approach is to call the batch file with a .vbs script. I was using an SFTP command line client some time back and it always seemed to hang when trying to call it using a batch file or directly (it was waiting for input on the command line). So, I ended up CFEXECUTE-ing a .vbs script on the command line and it worked great.

       <cfset exec = 'C:\windows\system32\cmd.exe'>   
       <cfset args = '/c "#serverPath#ftp.vbs"; 2>&1'>

       <cfexecute timeout="15" name='#exec#'

    Yep passing args in win batch files. The way I handled similar issue can be seen here:

    @Eapen - Hi yeah I used to write VBS files for parsing EMail Attachments from Exchange but I felt that the batch script was "fit-for-purpose" on this occasion - fingers crossed I don't experience any issues!

    @spills - Hi, interesting, I suppose it's a matter of preference whether you wish to pass your arguments "inline" or predefine them in an array.

    Thanks for sharing ;-)
