[slurm-users] Executing slurm command from Lua job_submit script?

[Marcus Wagner]

Hi Chansup,

os.execute just returns the EXIT code of the command.

You will need to do a little more, to catch the output of your program, e.g.

function shellExecute(cmd, Output)
    if (Output == nil) then Output = true end
    local file = assert(io.popen(cmd, 'r'))
    if (Output == true) then
       local cOutput = file:read('*all')
       file:close()
       return cOutput
    else
       file:close()
       return
    end
end


Sorry for the delay, I`m on easter holidays and did not follow the list.

Best
Marcus
