Powershell: passing parameters to a job

Question

I have a script that requires a number of parameters:

param ([string]$FOO=\"foo\",[string]$CFG=\'\\ps\\bcpCopyCfg.ps1\', [string]$CFROM=\"none\", `
[string]$         


        

Answer 1

Another way is to put the @ before the array. I changed the $ARGS variable to $flags to differentiate $args in the scriptblock from $flags.

$flags = @("-CFG ", $CFG, "-CSYBDB ", $SYBDB, "-CMSDB ",$MSDB, "-CFROM ", $SYBTBL, "-CTO ",$MSTBL)

If($FULL) {
    $flags = $flags + " -FULL"
}
Else {
   $flags = $flags + " -CCOL $($args[5])  "
}
"Argument array:"
$flags

start-job  -scriptblock {powershell.exe -file '\ps\bcpCopy.ps1' $args} -ArgumentList $flags

Answer 2

I'm not sure what exactly you're trying to do, but this looks wrong:

start-job  -scriptblock {
    powershell.exe -file '\ps\bcpCopy.ps1'} -ArgumentList $ARGS

You are creating an entirely new powershell process needlessly. Try this instead:

start-job  -scriptblock {
    & 'c:\ps\bcpCopy.ps1' @args } -ArgumentList $ARGS

The "@args" syntax is called "splatting." This will expand the passed arguments and ensure each element is treated as a parameter. The ampersand (&) is the "call" operator.
