SCVMM - passing linux commands throuhg GuiRunOnceCommands to created VM from temaple

Hello Team,

I have created a Oracle Linux template in SCVMM, and i'm using SCVMM powershell command to automate VM creation, also I passed some echo commands through GuiRunOnceCommands, but seems not all commands mentioned in the -GuiRunOnceCommands are running in the created VM,

for example, touch command works fine, but echo command to write on file does not work,

do I have to add some prefixing to the command to make it running?

I do appreciate you help

Thanks
