Hopefully someone can help me out.
I currently run a script that cleans up file names by using:
get-childitem -recurse | dir -Filter *.mp4 | Rename-Item -NewName { $_.BaseName.replace('Oldname','NewName') + $_.Extension }
It has a ton of extra words and stuff piped in and works very well. I'm making a new script using this method, but I'm left with a trailing white space at the end of each file.
From what I can see Trim should do what I need:
.Trim()
As I understand it should remove any leading and trailing white spaces.
I was thinking of just removing all white spaces, but the problem with that is some filenames will have multiple words separated by white spaces.
So I thought that a loop may do the trick, but as I'm still new to Powershell I can't quite work it out.
Long story short, I'm looking to run a recursive scan on all files in a directory, specifically MP4 and MKV, then for each file in the directory, apply trim to it so it will remove any trailing white spaces.
Any help with this would be greatly appreciated!
Perfect answer from Doug Maurer. I just needed to add the trim at the end of my commands, I think I was just placing it wrong, then thinking I needed to loop it. The answer is far more simple.
Before anyone says something, I know this isn't the most elegant script, but I does what I need it to. It's used to find specific words in file names, and remove them and replace them with nothing. However, once done, sometimes I'm left with a trailing white space.
By adding trim to the end, before adding the extension back on, it removes the space perfectly for my use case.
get-childitem -recurse | dir -Filter *.mp4 | Rename-Item -NewName { $_.BaseName.replace('Name1','').replace('Name2','').replace('Name3','').replace('Name4','').replace('Name5','').replace('Name6','').replace('Name7','').replace('Name8','').Trim() + $_.Extension }
With Doug's suggested edit of removing DIR as it's unnecessary:
Get-ChildItem -Recurse -Filter *.mp4 | Rename-Item -NewName { $_.BaseName.replace('Name1','').replace('Name2','').replace('Name3','').replace('Name4','').replace('Name5','').replace('Name6','').replace('Name7','').replace('Name8','').Trim() + $_.Extension }
You don't have trim in there so I can't say why your attempts have not worked. What I can say is that you don't need two DIR commands, (dir is alias for Get-ChildItem). It seems your command is missing the part where you add the extension back to the name and the final curly brace. The following will trim the basename like you describe.
Get-ChildItem -Recurse -Filter *.mp4 |
Rename-Item -NewName {$_.BaseName.replace('Oldname','NewName').Trim() + $_.Extension}

I have a folder that contains files like 'goodthing 2007adsdfff.pdf', 'betterthing 2007adfdsw.pdf', and 'bestthing_2007fdsfad.pdf', I want to be able to rename each, eliminating all text including 2007 OR _2007 to the end of the string keeping .pdf and getting this result: 'goodthing.pdf' 'betterthing.pdf' 'bestthing.pdf' I've tried this with the "_2007", but haven't figured out a conditional to also handle the "2007". Any advice on how to accomplish this is greatly appreciated.
Get-ChildItem 'C:Temp\' -Name -Filter *.pdf | foreach { $_.Split("_2017")[0].substring(0)}
Try the following:
Get-ChildItem 'C:\Temp' -Name -Filter *.pdf |
Rename-Item -NewName { $_.Name -replace '[_ ][^.]+' } -WhatIf
Note: The -WhatIf common parameter in the command above previews the operation. Remove -WhatIf once you're sure the operation will do what you want.
The above uses Rename-Item with a delay-bind script block and the -replace operator as follows:
Regex [_ ][^.]+ matches everything from the first space or _ char. (character set [ _]) through to the following literal . char. ([^.]+ matches one or more chars. other than (^) than .) - that is, everything from the first / _ through to the filename extension (excluding the .).
Note: To guard against file names such as _2017.pdf matching (which would result in just .pdf as the new name), use the following regex instead: '(?<=.)[_ ][^.]+'
By not providing a replacement operand to -replace, what is matched is replace with the empty string and therefore effectively removed.
The net effect is that input files named
'goodthing 2007adsdfff.pdf', 'betterthing 2007adfdsw.pdf', 'bestthing_2007fdsfad.pdf'
are renamed to
'goodthing.pdf', 'betterthing.pdf', 'bestthing.pdf'
Without knowing the names of all the potential files, I can offer this solution that is 100%:
PS> $flist = ("goodthing 2007adsdfff.pdf","betterthing 2007adfdsw.pdf","bestthing_2007fdsfad.pdf")
PS> foreach ($f in $flist) {$nicename = ($f -replace "([\w\s]+)2007.*(\.\w+)", '$1$2') -replace "[\s_].","." ;$nicename}
goodthing.pdf
betterthing.pdf
bestthing.pdf
Two challenges:
the underscore is actually part of the \w character class. So the alternative to the above is to complicate the regex or try to assume that there will always be only one '_' before the 2007. Both seemed risky to me.
if there are spaces in filenames, there is no telling if you might encounter more than one. This solution removes only the one right before 2007.
The magic:
The -replace operator enables you to quickly capture text in () and re-use it in variables like $1$2. If you have more complex captures, you just have to figure out the order they are assigned.
Hope this helps.
I have files look like
data.svg
map.svg
aplicationp.svg
...
*.svg
I am trying to add -b string to the end of all files names bu using power shell rename command like
D:\icons> Dir | Rename-Item -NewName {$_.name -replace ".","-b."}
to get these
data-b.svg
map-b.svg
application-b.svg
but this is not changing anything. How can I achieve this?
Powershell's -replace operator is based on regular expressions. And since . is a wildcard in regex, what should be happening is that each character in the file name is being replaced with the resulting string. So test.txt would become -b.-b.-b.-b.-b.-b.-b in your example.
You likely want to use the Replace method of the .NET String type like this instead.
dir | Rename-Item -NewName { $_.Name.Replace('.','-b.') }
If you want to keep using -replace, you need to escape the . in your expression like this.
dir | Rename-Item -NewName { $_.Name -replace '\.','-b.' }
Both of these have a couple edge case problems that you may want to avoid. The first is narrowing the scope of your dir (which is just an alias for Get-ChildItem) to avoid including files or directories you don't actually want to rename. The second is that a simple replace in the file name doesn't account for file names that contain multiple dots. So you may want to ultimately do something like this if you only care about SVG files that may have multiple dots.
Get-ChildItem *.svg -File | Rename-Item -NewName { "$($_.BaseName)-b$($_.Extension)" }
The replace operator uses regex. Therefore your . needs to be escaped, otherwise it just stands for any character. I would generally make sure to be as specific as possible when writing regexes. The following is a possible solution
Get-ChildItem *.svg | Rename-Item -NewName { $_.name -Replace '\.svg$','-c.svg' }
The $ anchors the expression to the end of the string which makes sure it only changes the extension and not any other text inside the file names.
I have 1000 PDFs in a folder C:\Users\1003911\Desktop\pdf.
File names are something like 38852ad-Layout1, 38852s-Layout-1, and so on.
I need to remove "-Layout1" from all the PDFs.
I tried few options from this site, but I cannot get it right. Anyone can give me exact code what I should write?
My code is:
Get-ChildItem 'C:\Users\1003911\Desktop\pdf' |
Rename-Item -NewName { $_.Name.Substring(0, $_.Name.Length-12) }
I used this to rename and it worked, but the .pdf extension is removed. How do I retain it?
You got the right idea. I personally think it's easier to use $_.basename and put it in a sub-expression and tack on the .pdf at the end.
Get-ChildItem C:\Users\1003911\Desktop\pdf | rename-item -newname {"$($_.basename.Replace('-layout1','')).pdf"}
also note, I used [string] replace method instead to remove the "-layout1"
Hope this helps :)
Other version of Ricc solution:
Get-ChildItem "C:\Users\1003911\Desktop\pdf" -file -filter "*.pdf" | rename-item -NewName {$_.Name.Replace('-layout1','')}
This version :
Take only file, not directory
Filter on pdf only
Rename Name and not BaseName + concatenation
I need to rename around 5000 files that have the following naming format:
"322xxx-710yy.tiff"
i need to remove -710yy from the name to get 322xxxx.tiff
can anyone suggest a rename-item command for power-shell to do this?
i tried:
get-childitem -filter "322*" -recurse | Rename-item -NewName{$_.name -replace '-710*', ''}
but all that does is remove the "710" leaving the remaining characters after it.
-replace takes a regex, not a wildcard match (unlike the -Filter parameter of Get-ChildItem), so you need
$_.Name -replace '-710[^.]*'
instead (you can also leave out the , '' in that case, as it's implied). Note that I'm only replacing non-dot characters after the 710, to keep the extension intact.
Can someone tell me why this script won't work?
Get-ChildItem "\\fhnsrv01\home\aborgetti\Documentation\Stage" -Filter *.EDIPROD | `
Foreach-Object{
$content = Get-Content $_.FullName
#filter and save content to a new file
$content | Where-Object {$_ -match 'T042456'} | Rename-Item `
($_.BaseName+'_834.txt')
I found this syntax from another question on here and changed the environment variables.
For some reason it won't change the name of the file. The filename is
'AIDOCCAI.D051414.T042456.MO.EDIPROD'
Help much appreciated.
UPDATE
Thanks to TheMadTechnician I was able to get some working stuff. Great stuff actually. Figure I should share with the world!
#Call Bluezone to do file transfer
#start-process "\\fhnsrv01\home\aborgetti\Documentation\Projects\Automation\OpenBZ.bat"
#Variable Declarations
$a = Get-Date
$b = $a.ToString('MMddyy')
$source = "\\fhnsrv01\home\aborgetti\Documentation\Stage\"
$dest = "\\fhnsrv01\home\aborgetti\Documentation\Stage\orig"
#Find all the files that have EDIPROD extension and proceed to process them
#First copy the original file to the orig folder before any manipulation takes place
Copy-item $source\*.EDIPROD $dest
# Now we must rename the items that are in the table
Switch(GCI \\fhnsrv01\home\aborgetti\Documentation\Stage\*.EDIPROD){
{(GC $_|Select -first 1) -match "834*"}{$_ | Rename-Item -NewName {$_.BaseName+'_834.txt'}}
{(GC $_|Select -first 1) -match "820*"}{$_ | Rename-Item -NewName {$_.BaseName+'_820.txt'}}
}
Get-ChildItem's -Filter has issues, I really hesitate to use it in general. If it were up to me I'd do something like this:
Get-ChildItem "\\fhnsrv01\home\aborgetti\Documentation\Stage" |
?{$_.Extension -match ".EDIPROD" -and $_.name -match "T042456"}|
%{$_.MoveTo($_.FullName+"_834.txt")}
Well, I would put it all on one line, but you can line break after the pipe and it does make it a little easier to read, so there you have it. I'm rambling, sorry.
Edit: Wow, I didn't even address what was wrong with your script. Sorry, kind of distracted at the end of my work day here. So, why doesn't your script work? Here's why:
You pull a file and folder listing for the chosen path. That's great, it should work, more or less, I have almost no faith in the -Filter capabilities of the file system provider, but anyway, moving on!
You take that list and run it through a ForEach loop processing each file that matches your filter as such:
You read the contents of the file, and store them in the variable $content
You run the contents of the file, line by line, there a Where filter looking for the text "T042456"
For each line that matches that text you attempt to rename something to that line's basename plus _834.txt (the line of text is a string, it doesn't have a basename property, and it's not an object that can be renamed, so this is going to fail)
So, that's where the issue is. You're pulling the contents of the file, and parsing that line by line trying to match the text instead of matching against the file name. If you removed Everything after the first pipe up to the Where statement, and then for your rename-item put -newname before your desired name, and change the ( ) to { } that goes around the new name, and you would be set. Your code would work. So, your code, modified as I said, would look like:
Get-ChildItem "\\fhnsrv01\home\aborgetti\Documentation\Stage" -Filter *.EDIPROD |
Where-Object {$_ -match 'T042456'} | Rename-Item -NewName {$_.BaseName+'_834.txt'}
Though I have a feeling you want $.Name and not $.BaseName. Using $_.BaseName will leave you with (to use your example file name):
'AIDOCCAI.D051414.T042456.MO_834.txt`
Edit2: Really that's a whole different question, how to match multiple criteria, but the question is here, I'm here, why not just get it done?
So, you have multiple criteria for matching the file names. That really doesn't affect your loop to be honest, what it does affect is the Where statement. If you have multiple options what you probably want is a RegEx match. Totally doable! I'm only going to address the Where statement (?{ }) here, this won't change anything else in the script.
We leave the extension part, but we're going to need to modify the file name part. With RegEx you can match against alternative text by putting it in parenthesis and splitting up the various options with a pipe character. So it would look something like this:
"(T042456|T195917|T048585)"
Now we can incorporate that into the rest of the Where statement and it looks like this:
?{$_.Extension -match ".EDIPROD" -and $_.name -match "(T042456|T195917|T048585)"}
or in your script:
Where-Object {$_ -match "(T042456|T195917|T048585)"}
Edit3: Hm, need the first line for the qualifier. That complicates things a bit. Ok, so what I'm thinking is to get our directory listing, get the first line of each file with the desired extension, make an object that has two properties, the first property is the fileinfo object for the file, and the other property will be the first line of the file. Wait, I think we can do better. Switch (GCI *.EDIPROD){(get-content|select -first 1) -match 820}{Rename 820};{blah blah -match 834}{rename 834}}. Yeah, that should work. Ok, actual script, not theoretical gibberish script time. This way if you have other things to look for you can just add lines for them.
Switch(GCI \\fhnsrv01\home\aborgetti\Documentation\Stage\*.EDIPROD){
{(GC $_|Select -first 1).substring(177) -match "^834"}{$_ | Rename-Item -NewName {"834Dailyin$b"};Continue}
{(GC $_|Select -first 1).substring(177) -match "^820"}{$_ | Rename-Item -NewName {$_.BaseName+'_820.txt'};Continue}
}
Again, if you want the EDIPROD part to remain in the file name change $_.BaseName to $_.Name. Switch is pretty awesome if you're trying to match against different things and perform different actions depending on what the results are. If you aren't familiar with it you may want to go flex your google muscles and check it out.
Hm, alternatively we could have gotten the first line inside the Where filter, run a regex match against that, and renamed the file based on the regex match.
GCI \\fhnsrv01\home\aborgetti\Documentation\Stage\*.EDIPROD | ?{(GC $_ | Select -First 1) -match "(820|834)"}|Rename-Item -NewName {$_.Name+"_"+$Matches[1]+".txt"}
Then you just have to update the Where statement to include anything you're trying to match against. That's kind of sexy, though not as versatile as the switch. But for just simple search and rename it works fine.
Try it like this way
Get-ChildItem -Filter "*T042456*" -Recurse | % {Rename-Item $_ "$_ _834.txt"}
