winexe gets stuck in some remote servers

[amrithgnair]

I want to be able to create a timeout such that the winexe stops executing in the remote server and returns control back to shell where it was initiated:

I am trying this:

x=winexe -U user%pwd //vservername 'powershell.exe Get-WmiObject Win32_ComputerSystem | Select-Object -ExpandProperty NumberOfLogicalProcessors'

In some systems the command gets stuck in the remote system and does not come back, I would like to add a timeout to the above command, I tried this

x=timeout 10 winexe -U user%pwd //vservername 'powershell.exe Get-WmiObject Win32_ComputerSystem | Select-Object -ExpandProperty NumberOfLogicalProcessors'

but does not work.

Please help

I also tried this, but when command is successful value of z is not set:

z=winexe -U domain/user%pwd //vservername 'cmd /C powershell.exe "Get-WmiObject Win32_ComputerSystem | Select-Object -ExpandProperty NumberOfLogicalProcessors"' & sleep 5;kill $!
