How to add space in many file names - powershell

I was trying to remove all the underscores, spaces and square brackets from many animation files name, which made a big mess.
I used the code below to replace/remove the characters with what I want.
Replace
Get-ChildItem -Filter "*One Piece_*" -Recurse |
Rename-Item -NewName {$_.Name -replace 'One Piece_','One Piece '}
Or (to delete space)
Get-ChildItem -Filter "* *" -Recurse |
Rename-Item -NewName {$_.Name -replace ' ',''}
Now all the file names look like this:
One Piece 031EEE7A115 → should be One Piece 031 EEE7A115
One Piece 032FFB90605 → should be One Piece 032 FFB90605
etc.
Is there a way to insert space to all the files after the episode number?

Sure. Make a regular expression that matches the substring from the beginning of the name up to three consecutive digits, and replace that with itself and a space:
Get-ChildItem -Filter '*One Piece_*' -Recurse |
Rename-Item -NewName {$_.Name -replace '^(.*?\d{3})', '$1 '}

Counting .csv files based on their first n number of characters

I need to write a script that checks the first 3 to say 5 characters of a .csv file, then count those files and report the characters with the corresponding count.
I already have a few methods to do the simpler tasks. I've used a filter before to only select certain .csvs, using this:
Get-ChildItem C:\path -Recurse -Filter *.csv | Where {$_.Name -match 'NNN'}
I also use this to count the number of csvs in that corresponding location:
(Get-ChildItem C:\path -Recurse -Filter *.csv | Measure-Object).Count
How can I run a scan through a folder with say 3 random titles for the csv? Say they're RUNxxxxxxxx.csv, FUNxxxxxxx.csv, and TUNxxxxxxx.csv.
Edit: Let me explain more; basically, the example csvs I have above would be completely random, so it'd need to recognize those first 3 are different and only count those.
I'm not sure if a prompt inputting these would do any. The values are known, just different week to week (which is when this would be run;every week)
Thanks!
You can accomplish that using the where-object filter combining three or statements which finds anything starting with the three letters you want and a wild card after.
Get-ChildItem C:\path -Recurse -Filter *.csv | Where {$_.Name -like "RUN*" -or $_.Name -like "Fun*" -or $_.Name -like "TUN*"}
You could also use the get-childitem -filter to accomplish this instead of searching for all .csv files and then use where-object.
Get-ChildItem C:\path -Recurse -Include "fUN*.csv","RUN*.csv","Tun*.csv"
How about using a calculated property to add the desired part as additional property to be able to work with it?
$PatternList =
'run',
'fun',
'tun'
Get-ChildItem -Recurse -Filter *.csv |
Select-Object -Property #{Name = 'Part'; Expression={($_.Name).substring(0,3)}},* |
Where-Object -Property Part -In -Value $PatternList |
Group-Object -Property Part

Rename-Item renaming issue

I am wrote some code and the first time it worked fine. However, I've now replaced the files with new dummy files and I'm now getting the following:
MyTestFile.zip is changed to MyTestFile_zip.zip_zip.zip
MyTestFile.prd is changed to MyTestFile_prd.prd_prd.prd
Here's the code:
Get-ChildItem -Filter "*.prd" -Recurse | Rename-Item -NewName {$_.name -replace '.prd','_prd.prd'}
Get-ChildItem -Filter "*.zip" -Recurse | Rename-Item -NewName {$_.name -replace '.zip','_zip.zip'}
Got any ideas how I can avoid this problem?
Thanks
The -replace operator
takes a regular expression as its first operand and
performs substring matching by default.
Therefore, you must modify the regex that is the first operand for the replacement to work as intended:
$_.Name -replace '\.prd$','_prd.prd'
. is escaped as \. to make sure that -replace treats it as a literal; without the \, . would match any character.
$ ensures that the expression is anchored to the end of the input, i.e., only matches at the end.
A more generic reformulation that covers both .prd and .zip:
$_.Name -replace '\.(prd|zip)$','_$1.$1'
See below for an explanation.
If we put this all together, we can get away with a single pipeline:
Get-ChildItem -File *.prd, *.zip -Recurse |
Rename-Item -NewName { $_.Name -replace '\.(prd|zip)$','_$1.$1' }
Use of regular expressions allows you to process more than one extension at a time, and also allow you to reference parts of what the regular expression matched (captured) through capture groups (parenthesized subexpressions) that you can reference as $1 (1st capture group, ...) in the replacement string
> #( 'example.zip', 'example.prd' ) -replace '\.(prd|zip)$','_$1.$1'
example_zip.zip
example_prd.prd
Note how $1 in the replacement string refers to whatever capture group (prd|zip) captured, which is zip for the first input, and prd for the second.
Editor's note:
While this answer doesn't work for the specific question at hand, because it inserts an extraneous ., it does show the use of [System.IO.Path]::ChangeExtension() as a robust way to change a file's extension in general.
Alternatively use the .net method to change the file extension:
Get-ChildItem -Filter "*.prd" -Recurse | Rename-Item -NewName {[System.IO.Path]::ChangeExtension($_.name,"_prd.prd")}

remove random text from file name

I have a folder full of files which have had some text prepended to the filenames. For example:
program1.m has become John Smith 23423_file_program1.m.
program2.m has become Jane Doe 235_file_program2.m.
The number of characters that have been prepended is not consistent, but the substring file_ is always the final set of characters I wish to remove. Is there anyway to remove all characters up to and including the file_ in a folder full of files? This was my attempt, but as expect the * does not work in this scenario:
get-childitem *.m | foreach { rename-item $_ $_.Name.Replace("*file_","") }
This should do the trick. There are other ways to do this as well so don't be surprised if you find another one.
get-childitem *.m -Filter *.m | ForEach{
Rename-Item -Path $_.FullName -NewName ($_.Name -replace ".*file_")
}
Or shorter
get-childitem -Filter *.m | Rename-Item -NewName {$_.Name -replace ".*file_"}
You had the right idea but the issue you have is the string .replace() method is looking to match static strings and does not use wildcards. The way you had it it expected an asterisks to appear in the string which one did not.
Instead we use -replace which supports regex. .*file_ would satisfy the requirement of remov[ing] all characters up to and including the _file. Since you just want it removed we don't offer a replacement string.
If regex is not your friend you should try and warm up to him. If not some old school methods work just as well.
$file = "blah_file_program.m"
$file.Substring($file.LastIndexOf("_") + 1)
program.m

bulk rename using powershell to get rid of 9 characters that follow a "-"

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.

Why won't it rename the file? Powershell

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"}
