Lessons from a Simple Task - Using the Pause Command in a Batch File


Just today, I made myself work a lot harder than was ever necessary.  It started with a little bit of overconfidence, transitioned to about thirty minutes of frustration and swearing, and ended with success and a self deprecating laugh.

It started when I need to create a sample script to defragment an Autodesk Vault database.

How hard can it be, after all?  It's a short script.  It's only a few lines long anyway!

First, I grab the sample script from the Vault Help system.  You can find that in the defragment section at this link.

So now I have my command!

 Connectivity.ADMSConsole.exe -Odefragmentvault -NVault -VUAdministrator -VPadmin -S

This will fire up the command, but I still need to add my path information as well as my Vault name, I also need to add my administrator username and password.

REM - This Script Defrags the VAult Database
REM - Switch Legend
REM - Odefragmentvault ==> Command to defrag database
REM - -N Designates Vault name (this will vary machine to machine)
REM - -VU Vault user (must have administrator rights)
REM - -VP Vault password
REM - -S runs the script silently

D:\Program Files\Autodesk\ADMS Professional 2015\ADMS Console\Connectivity.ADMSConsole.exe -Odefragmentvault -NArduinna -VUadministrator -VP -S

So a little cutting and pasting I have the script I need.

Now, time for the test.

I run it once, it flashes on the screen and immediately disappears.

I check for syntax error, and I do find one.  Which I quickly fix.

But the script doesn't run.

I check my vault name, my administrator name.  My vault doesn't even have a password!

And for those of you with your mouse key on the comment button... I know it's bad practice not to have a password for the administrator!  But this is a personal Vault, on my laptop, which only I access.  So Thpppt! 

Finally, I have an idea.  One that I should have had a lot earlier than I did..

I add the word Pause at the end of my script.  So the script won't disappear when it finishes.

Let's take a second and think about this.

As soon as I run the script.  I see two words immediately. "Not Recognized".

I say phrases commonly found in garages, aircraft hangars, and factories everywhere.

The double quotes at the each end of the path are missing!

Wait! What? This is the problem! 
I look at my reflection in my computer screen.  "You Idiot!"  I shout, channeling my inner Ren.

It felt a little like this.
(From the Ren & Stimpy Show)
I should have known!  When running a command with spaces in it, you have to put the command inside of quotes.

If you don't , the script reaches the first space it sees, and tries to execute that.

So my batch file got to D:\Programs, tried to run that, and didn't know what to do.

In order to fix the script, I had to change the command line to look like what is below:

"D:\Program Files\Autodesk\ADMS Professional 2015\ADMS Console\Connectivity.ADMSConsole.exe" -Odefragmentvault -NArduinna -VUadministrator -VP -S

The quotes (in red) placed before D:\Program and after ADMSConsole.exe make all the difference in the world.

One more shot, and it runs fine!

So the final script looks like this.

REM - This Script Defrags the Vault Database
REM - Switch Legend
REM - Odefragmentvault ==> Command to defrag database
REM - -N Designates Vault name (this will vary machine to machine)
REM - -VU Vault user (must have administrator rights)
REM - -VP Vault password
REM - -S runs the script silently

"D:\Program Files\Autodesk\ADMS Professional 2015\ADMS Console

\Connectivity.ADMSConsole.exe" -Odefragmentvault -NArduinna -VUadministrator -VP -S

IISRESET

And that's it! It's ready to go.

Ultimately, what did I take a way from this one?
  • Use the PAUSE command to help analyze scripts.  Because it was a short script, I figured if I studied it, I could find my error.  But I didn't see the missing quotes. I missed the trees because of the forest, if you will. By adding the PAUSE command, I found my error in seconds.  Literally seconds! 
  • Slow down, you'll go faster.  Since this was an easy script, I thought I'd "bust it out quick".  Had I taken a little more time, and thought about my approach when I hit a snag, I may have solved it easier. 
  • Pay it forward.  I made a mistake.  One I should  have been able to avoid.  Here it is for you to learn from.  Hopefully, you can use this to avoid the pitfalls I found! 
On a final note, there are several administrative commands that can be scripted using batch files in Autodesk Vault.
