$LocalWorkspace = $LocalWorkspace -replace "`n|`r"

# Set P4Ignore to Dev Path P4Ignore
$P4IgnorePath = Join-Path $LocalWorkspace "Dev"
$P4IgnorePath = Join-Path $P4IgnorePath "p4ignore.txt"

# Set Ignore
p4 set P4IGNORE=$P4IgnorePath

To unset your p4ignore.txt just have to set a path that doesn't exist.
