Question : I need some help with a batch file

I need some help with a batch file.

Here is the start:


@echo off
CLS
Echo Please wait, finding CommVault Test's moref...
Echo.
for /f "tokens=2 delims=:" %%x in ('C:\Progra~1\VMware\VMware~2\vcbvmname -h hostname -u username -p password -s Name:"CommVault Test" ^|find "vm-"') do (
echo Moref found: %%x
echo.
echo Please wait, creating snapshot...
C:\Progra~1\VMware\VMware~2\vcbSnapshot.exe -h hostname -u username -p password -c moref:%%x PreBackupSnapshot
)


Here is what I need changed/added:
1. I want to pass a machine name in.  Right now, you see "CommVault Test" throughout it, I want it changed to the variable.  For example, if the name of this batch file is preflight.cmd, then I would want to launch it using:
preflight "CommVault Test"

2. If the moref (a label that looks something like this: vm-2342) is not found, I want error handeling (display the error then quit).  The vcbvmame command will not return a line containing "vm-" if it is not found.

3. The vcbsnapshot line kicks off a command line routine that spits back a bunch of stuff.  I only want to see a line if it contains the word "Error" in it.  Also, if successful, it returns a line that contains "Ssid:snapshot-9999" where 9999 is some number (could be more than 4 digits).  If successful, I would like to see echoed:
Create snapshot successful.  SSID:9999

Answer : I need some help with a batch file

Here is my first attempt.  Please note that I don't have these programs or this environment, so I don't have a way to test this.  We will probably have to go back and forth a few times before we get it just right, but I have attempted to address all of your issues.  I forgot to ask about the format you want the SSID saved to the file in, so right now I just have it saving each SSID number to it's own line in a file in the current directory named SSID_List.txt.  

Here is the code.  Let me know what happens, and if it actually works, let me know what is working the way you expect and what is not.

@echo off
setlocal
set Last=
CLS
Echo Please wait, finding %~1's moref...
Echo.
for /f "tokens=2 delims=:" %%x in ('C:\Progra~1\VMware\VMware~2\vcbvmname -h hostname -u username -p password -s Name:"%~1" ^|find "vm-"') do (
   set Last=%%x
   if  {%%x}=={} goto :EOF
   echo Moref found: %%x
   echo.
   echo Please wait, creating snapshot...
   C:\Progra~1\VMware\VMware~2\vcbSnapshot.exe -h hostname -u username -p password -c moref:%%x PreBackupSnapshot
   findstr /i "error" Snap.tmp >NUL
   if not errorlevel 1 (echo Create Snapshot failed.  Error message is:
      findstr /i "error" Snap.tmp
      ) else (
      for /f "tokens=4 delims=-" %%y in ('findstr /i "ssid" Snap.tmp') do (
         echo Create snapshot successful.  SSID:%%y
         echo %%y >>SSID_List.txt
         )
      )
   )
if exist Snap.tmp del Snap.tmp
if {%Last%}=={} echo No labels found
