Overwrite Destination With Powershell

Answered Overwrite Destination With Powershell

    I am a novice PowerShell user but I found a short command to copy one file to another location:

    [System.IO.File]::Copy("I:\All\Applications\Schedule\directoryname\filename.xls","C:\Users\username\directoryname\Documents\Cabot S\filename.xls");

    It works fine but only for the initial copy. I need it to overwrite each time we run the script. I have made an exhaustive search for this answer and oddly enough, I cannot find the correct syntax I need to do this.

    Suggestions?
    Thanks!
    Brian

    Why use the IO.File Copy method when you can just use the copy-item cmdlet?

    I also tried this:

    Copy-Item -force("I:\All\Applications\Schedule\directoryname\filename.xls","C:\Users\username\directoryname\Documents\Cabot S\filename.xls"); and I didn't get an error but the destination didn't seem to change and if I deleted the file at the destination, this script will not copy the file at all.

    There is a File.Copy() overload that allows you to specify if you want to overwrite the destination file if it exists:

    File.Copy Method (String, String, Boolean)

    But you should look into the Copy-Item cmdlet first:

    Copy-Item

    I am a novice and it was the first command I found.

    Sorry...being a novice, that is all greek to me...I thought it would be easy to copy a file and overwrite it with a PowerShell command. I looked over that second article and nothing made enough simple sense to help me overwrite the destination.

    Try this:

    Copy-Item -path 'I:\All\Applications\Schedule\directoryname\filename.xls' -Destination 'C:\Users\username\directoryname\Documents\Cabot S\filename.xls' -Force

    Also see

    get-help copy-item -full

    [string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

    OK, have a look at this article:

    Files and Folders, Part 3: Windows PowerShell

    Lots of examples there.

    Thanks for the nudges...going to try the test-path remove-item commands and see if it helps.

    Note that copy-item will overwrite the destination without prompting by default. The only problem you may run into is if the destination file is read-only (-force will take care of that), or if the file is open, in which case the only remedy is to close the file first, then overwrite it.
