IMPORTANT: PowerShellCommunity.org is moving! - Wednesday, August 15, 2012

PowerShellCommunity.org is moving!  This community software, and the hardware that it sits on, are no longer serving the purposes of this community.  As a result, we have decided to move this community to a new home at PowerShell.org.  PowerShell.org is already up and running with the new community software and in its new location, so please post any new questions that you have on the forums over there instead of posting them on this site.  We've already started getting some great questions from members of the community over there so please, come on over and join us!

While we are going through this transition, this site will remain up for the short term.  New posts may no longer be created on these forums, however replies to existing posts are allowed so that users who posted questions don't have to re-post the same question on the new site.

[UPDATE 28/02/2013] New user registration has been disabled and forums have now been switched to read-only, including for existing posts since all threads that were started should now be completed. If you have a question about content on this site or about PowerShell in general, head over to PowerShell.org and ask it there where there are people actively using the site and answering questions.

If you have any questions, please let us know on the PowerShell.org site.

Thank you,

Kirk "Poshoholic" Munro

    Hi all,

    I have thousands of gif files which need to be analyzed.
    All filenames have following structure: pic_text1_text2_ok.gif

    I want to replace text1 to text2 and vica versa, so in the end all filenames should look like pic_text2_text1_ok.gif
    These text1 and text2 parts can have a different length in characters (from 1 to 3 characters).

    How can I do this recursively?

    thanks in advance!

    If you have a string like this:

    $oldName = "pic_text1_text2_ok.gif"
    $newName = $oldName -replace '(.*_)(.*)(_)(.*)(_.*)', '$1$4$3$2$5'
    "Look Ma...no strings!"
