Write-Host -NoNewline “Enabling feature XYZ…….”
$a=”This”, ‘Is’, ‘a’, ‘cat’ Using double quotes (and optionally use the separator $ofs) # This Is a cat “$a” # This-Is-a-cat $ofs=”-” # after this all casts work this way until $ofs changes! “$a” Using operator join # This-Is-a-cat $a -join ‘-‘ # ThisIsacat -join $a Using conversion to [string] # This Is a cat … Read more
In order to find the location of a script, use Split-Path $MyInvocation.MyCommand.Path (make sure you use this in the script context).
