Send Multiple Commands to External Program

Since redis-cli appears to read input from STDIN you could feed it an array with the command strings like this:

'MULTI', 'EXEC' | & redis-cli -h localhost -p 6379

Using echo (alias for Write-Output) is not required for feeding the array into the pipeline.

You could also store the command array in a variable first:

$cmds = 'MULTI', 'EXEC'$cmds | & redis-cli -h localhost -p 6379
