Hi,

I am getting "No such file or directory" for the below script when using Invoke-VMScriptPlus v3. Please help!!

Script

$pScript = @'
'/usr/bin/df -h'
echo
'cat /etc/redhat-release'
echo
uname -a
echo
pwd
'@

$sCode = @{
VM = "disktest"
GuestOS = 'Linux'
GuestCredential = $Cred
SkipCertificateCheck = $true
Verbose = $true
NoIPinCert = $true
ScriptType = 'bash'
ScriptText = $pScript
}

[LucD · Accepted solution]

Can you try without the quotes?

$pScript = @'
/usr/bin/df -h
echo
cat /etc/redhat-release
echo
uname -a
echo
pwd

Hi LucD,

That worked now. But when I try outfile parameter, I am getting the below error

$sCode = @{
VM = "disktest"
GuestOS = 'Linux'
GuestCredential = $Cred
SkipCertificateCheck = $true
Verbose = $true
NoIPinCert = $true
ScriptType = 'bash'
ScriptText = $pScript
OutFile = 'Myoutfile.txt'
}

The OutFile parameter copies a file from where the script is running in the Guest OS.
But that file has to exist.
In the error, it looks like this file 'my.txt' does not exist.

A good example is present in the function's Help.
It creates the file, and then that file is retrieved via the OutFile parameter.

$pScript = @'
  Get-Content -Path .\MyInput.txt | Set-Content -Path .\MyOutput.txt
'@
$sCode = @{
  VM = $VM
  GuestCredential = $cred
  ScriptType = 'powershellv7'
  ScriptText = $pScript
  InFile = 'C:\Test\MyInput.txt'
  OutFile = 'MyOutput.txt'
}
