Vista Tutorial - File name prefix?

In need to list a group of files, work on each one individually, then rename
each one with a different suffix when I've processed it. The listing and
looping parts I've done, but I can't find a way of (easily) just getting the
first part of a file's name. For example, I need to find and process
'C:\temp\firstfile.sql', then when I've finished with it, rename it
'C:\temp\firstfile.processed'. I can get the 'C:\temp' and '.sql' into
variables, but I really want the 'firstfile' part. Any ideas anybody?

Thanks in advance

Phew! That was quick! Thanks Marco and Hal, that does the job, but only in
CTP2. Is there no solution for V1.0 other than manually stripping off and
replacing the suffix? I haven't rolled CTP2 out into my production
environments.

That does it! Many thanks.

Hi Jacques,

You can rename files with move-item:


PS 9> new-item -type file -Name firstfile.sql

Mode LastWriteTime Length Name
---- ------------- ------ ----
-a--- 6/5/2008 3:58:56 PM 0.0 B firstfile.sql


PS 10> move-item firstfile.sql firstfile.processed
PS 11> dir *.pro*

Mode LastWriteTime Length Name
---- ------------- ------ ----
-a--- 6/5/2008 3:58:56 PM 0.0 B firstfile.processed



To get the first part of the filename:

PS 12> [io.path]::GetFileNameWithoutExtension("firstfile.sql")
firstfile


In PowerShell CTP(2) you can get the filename using the BaseName member:
PS 13> (dir .\firstfile.processed).BaseName
firstfile

Hi,

I'm new to powershell and having a similar problem where I'm trying to
rename the file with folder name as the prefix.

eg. C:\scripts\test.txt
becomes
C:\scripts\scripts_test.txt

I can get it to loop through and rename, but can't find a way to return the
folder name to append to the existing name?

Any advice is appreciated. Thanks

Hi,
I think you can get the folder name like this:
((gci C:\scripts\test.txt).directory).name

"scripts " should be return.

Hi Megan,


Here's a sample to rename all files in c:\scripts directory, remove -whatIf
when you are ready to perform the rename:


# three files in c:\scripts

PS > dir c:\scripts

Mode LastWriteTime Length Name
---- ------------- ------ ----
-a--- 7/11/2008 13:33:10 0.0 B file1.txt
-a--- 7/11/2008 13:33:10 0.0 B file2.txt
-a--- 7/11/2008 13:33:10 0.0 B file3.txt


# get all files in c:\scripts, exclude directories, rename each file to 'parentDirectoryName_fileName.ext'

PS> dir c:\scripts | where {!$_.PSIsContainer} | rename-item -newName {$_.directory.name+"_"+$_.name}
-whatIf

What if: Performing operation "Rename File" on Target "Item: C:\scripts\file1.txt
Destination: C:\scripts\scripts_file1.txt".
What if: Performing operation "Rename File" on Target "Item: C:\scripts\file2.txt
Destination: C:\scripts\scripts_file2.txt".
What if: Performing operation "Rename File" on Target "Item: C:\scripts\file3.txt
Destination: C:\scripts\scripts_file3.txt".

Hi Megan,

Here's a slight variation on Shay's script that adds support for renaming
hidden files as well, plus it detects if some files already have the prefix
you want and skips them.

Get-ChildItem C:\Scripts -Force | Where-Object {(-not $_.PSIsContainer) -and
($_.name -notmatch "^$($_.directory
..name)_")} | Rename-Item -NewName {$_.directory.name + '_' +
$_.name} -Whatif

Be careful with the line wrap. This is a one-liner, so make sure you put it
on one line when you paste it into PowerShell.

This will allow you to run the script on the same folder over time as you
add files to it without worrying about it re-prefixing all of your files
that already have the prefix.
