Batch rename files in a directory by changing filenames

I have a large number of files in a directory with this type of naming convention: "[Date] [Lastname] 345.pdf". Note: 345 is constant for all of them

I would like to rename all files so that they read "[Lastname] [Date] 345.pdf".

Edit: I had a typo there

I've had some success:

gci -Filter *.pdf| %{Rename-Item $_.fullname $_.Name.Split(" ")[1]}

But that only gives me "[Date] .pdf". Basically, I can't figure out how to use the above command to combine two different split pieces. I basically want "[1] [0] [2] .pdf" if that makes sense.

Thank.

Another approach using regular expressions:

Get-ChildItem *.pdf | % {
  $newName = $_.Name -replace '^(.*) (\S+) (\S+\.pdf)$', '$2 $1 $3'
  Rename-Item $_ $newName
}

Regular Expression Distribution:



  • ^(.*)

    matches any number of characters at the beginning of a line and commits them to a group. [Date]

    in your example filename [Date] [Lastname] 345.pdf

    .
  • (\S+)

    matches one or more characters without spaces and captures them in the second group. [Lastname]

    in your example the filename [Date] [Lastname] 345.pdf

    .
  • (\S+\.pdf)$

    matches one or more consecutive non-whitespace characters, followed by a line .pdf

    at the end of the line, and captures this in the third group. 345.pdf

    in your example filename [Date] [Lastname] 345.pdf

    .

The groups are named $1

, $2

and $3

so the replacement string '$2 $1 $3'

reorders the groups the way you want.

Take a picture.



gci *.pdf| %{
    $Name = $PSItem.Name.Split(' ');
    $Dest = ('{0} {1} {2}' -f $Name[1], $Name[0], $Name[2]);
    Move-Item $PSItem.FullName -Destination $Dest;
};
