Guest Script Manager Help

I am having a problem getting the Guest Script Manager to execute a simple bash script:

cp /tmp/gg /tmp/gg2

Is there a reason why this bash command will not run?  Is it the way that it's being interpreted when it is passed...I'm unsure.  I am able to run this basic bash script:

sudo useradd [userName]

So I know that everything is working...just seems something is weird with how things are parsed when it runs.  Any ideas?

Hi,

Could you provide more details, like how exactly this script fails (errors/exceptions/stacktraces), how exactly do you start it (which workflow, what inputs, etc.), what is our environment (vRO version, etc.)?

vRO Version: 7.3.0.5481809

Test VM OS: CentOS Linux 7.3.1611

Inputs

Virtual Machine: name of test vm

Guest OS Username: root

Guest OS Password: ************

script type: bash

script: cp /tmp/gg /tmp/gg2

Script fails when I try to use the above command (any script input with /), however, workflow successfully completes with simple commands like mkdir or adduser so I know communication and workflow is working.  Seems like there is a problem with interpreting the syntax for the command cp /tmp/gg /tmp/gg2

You need to change the value of one of the input parameters - script context interactivity - from Yes/true to No/false.

Great...that helped the workflow complete without error(s), but it did not execute the script.  I can copy and paste the script command that it is passing into a SSH session with the VM and it completes fine.  Unsure what else it could be.

Hmm, I tested it in my environment (same vRO version, SuSE test vm), and it seems to work.

Could you test using the vRO appliance as the test vm (that is, test with SuSE instead of CentOS)? Also, which versions of Guest Script Manager and the corresponding workflows do you use?

Very strange, the script completed on the vRO appliance as the test VM per your suggestion.  I provisioned a fresh SuSE VM and tried to run it there, but no luck.  Workflow completes (green check) but does not carry out the script.

I am using guestscriptmanager-version-0.0.3 and for this example running the Run Script in Guest workflow

Have you tried using the functionality in the guest script manager that allows you to upload a script then execute it that way?  I've done this with some complex scripts that seemed to have issues.  When you create your script configuration just make the script that runs something like this.  Say you uploaded the script to ~/sometestscript.sh.  In the configuration make the script to run just a couple of lines:

chmod +x ~/sometestscript.sh

~/sometestscript.sh

You said SSH works? Have you tried using the Run SSH command workflow in place of Guest Script Manager? For Linux machines I think it's much cleaner to use that workflow versus GSM which requires VMware tools being installed. You don't have to track a PID with Run SSH command either; it should wrap up after the command is done invoking. I only use GSM for Windows devices.
