I have over 1000+ files that have to be renamed.
The first set folder and/or files are grouped by location, so the first four characters are the same for each file; there are four-five different locations. I need to delete the first few characters of the folder's name.
Example:
Old File: ABC_Doe, Jane
New File: Doe, Jane
any suggestions as to the quickest way to carry this out?
I've tried all of the following:
1st Attempt
$a = Get-ChildItem C:\example
$b = Where-Object {$_.name -like “*ABC_*”}
$cmdlet_name = “Rename-Item”
$d = (cmdlet_name $a $b)
invoke-expression $d
2nd Attempt
$e = Get-ChildItem C:\example
$f = $e.TrimStart (“ABC_”)
3rd Attempt
Rename-Item -{$_.name -like “*ASD*”, “”}
Try this, get all child items (files only), remove abc_ by replacing them (with nothing) and rename each file. To rename files in sub-directories add the -Recurse switch to the Get-ChildItem command:
Get-ChildItem c:\example -Filter ABC_* | Where-Object {!$_.PSIsContainer} | Rename-Item -NewName { ($_.BaseName -replace '^ABC_') + $_.Extension }
UPDATE
Actually, this should work as well and is much shorter (no need to append the file extension cause renaming is performed on the file name).
Get-ChildItem c:\example -Filter ABC_* | Where-Object {!$_.PSIsContainer} | Rename-Item -NewName { $_.Name -replace '^ABC_' }
get-childItem ABC_* | rename-item -newname { $_.name -replace 'ABC_','' }

Lets say I have a bunch of text files with people's names, that all have this as the content:
number
I want to replace "number" with a value from a CSV or text file, sequentially, and based on the file name. CSV has two columns, name and number:
Joe 5551011000
Gary 5551011001
Clark 5551011002
So I want to find the text file named Joe, and replace the "number" with "5551011000", and the text file named Gary, and replace "number" with "5551011001".
Thank you!
I didn't get too far:
Get-ChildItem "C:\test\*.txt" -Recurse | ForEach-Object -Process {
(Get-Content $_) -Replace 'changeme', 'MyValue' | Set-Content $_
}
This gets me party there, but I don't know how to find a specific file, then replace "number" in that file with the correct value that matches the name.
I also tried a different approach, with manual entry, and it works, but I need it to just be automated:
get-childitem c:\Marriott -recurse -include *.txt |
select -expand fullname |
foreach {
$new = Read-Host 'What is the new value you want for ' $_
(Get-Content $_) -replace 'number',$new |
Set-Content $_
}
I would convert your CSV to a hashtable, then this gets pretty simple.
$ReplaceHT = #{}
Import-Csv c:\path\to\file.csv -Delimiter ' ' -Header 'FileName','Number' | ForEach-Object {$ReplaceHT.add($_.FileName,$_.Number)}
Get-ChildItem c:\Marriott -recurse -include *.txt -PipelineVariable 'File'|Where{$_.name -in $ReplaceHT.Keys} |ForEach-Object{
(Get-Content $File.FullName) -replace 'changeme', $ReplaceHT[$File.Name] | Set-Content $File.FullName
}
I'm trying to search the contents of text files on remote computers from computers.txt which includes
Pc1
Pc2
Pc3
Pc4
And export it using export-excel PowerShell module
using this code:
$directory = $PSScriptRoot
$computers = Get-Content -Path $directory\computers.txt
$searchwords = 'word1','word2','word3'
Foreach ($computer in $computers) {
$path = "\\$computer\C$\test\logs"
Foreach ($sw in $searchwords) {
$excel = Get-Childitem -path $path -recurse -Include "*.txt" |
Select-string -pattern "$sw" |
Select-object pattern, linenumber, line, path |
Export-excel $file -autosize -startrow 1 -tablename pattern -worksheetname "errors" -passthru
$ws = $excel.workbook.worksheets['errors']
$excel.save()
}
}
The problem is that it will only export the contents of pc4 which is the last in the computers.txt list.
Thanks in advance
Adding the -append switch on export-excel will get this working.
It was added as part of the release on 10/30/2017 - https://github.com/dfinke/ImportExcel#whats-new-in-release-52
I try do write a script where i can choose a folder and powershell shows me the Name, Size,.... of all the files in that folder. After that powershell should export the Informations in a Excel Table.
But im stuck and dont know what to do :C
Here is my code that i tried to build
Function Get-Folder($initialDirectory)
{
[System.Reflection.Assembly]::LoadWithPartialName("System.windows.forms")|Out-Null
$foldername = New-Object System.Windows.Forms.FolderBrowserDialog
$foldername.Description = "Select a folder"
$foldername.rootfolder = "MyComputer"
if($foldername.ShowDialog() -eq "OK")
{
$folder += $foldername.SelectedPath
}
return $folder
}
$a = Get-Folder
$folder = $a
Get-ChildItem -Path $folder | SELECT Name, #{Name="Size In KB";Expression={$_.Length / 1Kb}}, Attributes, LastaccessTime, #{n='Owner';e={(get-acl $_.Fullname).Owner}}| Format-Table -AutoSize
Export-Csv "C:\Users\DZimmermann\Desktop\Test.csv" -Delimiter ";" -Append
As commented, using Format-Table -AutoSize simply outputs the info in a table format to console. It returns nothing, so there is nothing to write in the csv file..
Doing like this will create the CSV file and writes the info in there:
Get-ChildItem -Path $folder |
Select-Object Name,
#{Name="Size In KB";Expression={$_.Length / 1Kb}},
Attributes, LastaccessTime,
#{n='Owner';e={(get-acl $_.Fullname).Owner}} |
Export-Csv "C:\Users\DZimmermann\Desktop\Test.csv" -Delimiter ";"
This will not get you the info on screen. If you also want that, capture the result in a variable first:
$result = Get-ChildItem -Path $folder |
Select-Object Name,
#{Name="Size In KB";Expression={$_.Length / 1Kb}},
Attributes, LastaccessTime,
#{n='Owner';e={(get-acl $_.Fullname).Owner}}
#output on screen
$result | Format-Table -AutoSize
# write the CSV file:
$result | Export-Csv "C:\Users\DZimmermann\Desktop\Test.csv" -Delimiter ";"
P.S. judging by the title of this question, I think you only want info about Files, not Directories..
If that is the case, add -File switch to the Get-ChildItem cmdlet (for PS 3 and up). For PS versions below 3 use
Get-ChildItem -Path $folder | Where-Object { !$_.PSIsContainer }
I'm using PowerShell and it is two days that I'm struggling on this issue.
In the directory C:\dir_1 I have many subfolders (sub_1, sub_2, ..., sub_n). Each of them contains several text files. For each subfolder i=1,2,...,n, I want to move the text files that contain the string "My-String" to the directory C:\dir_2\sub_i.
For example, if the file X in the path C:\dir1\sub_5 contains the string "My-String", I want to move it to the location C:\dir_2\sub_5. The destination folder is already existing.
I tried several modifications of the following code, but it does not work:
Get-ChildItem "C:\dir_1" | Where-Object {$_.PSIsContainer -eq $True} | Foreach-Object {Get-ChildItem "C:\dir_1\$_" | Select-String -pattern "My-String" | group path | select name | %{Move-Item $_.name "C:\dir_2\$_"}}
So, basically, what I tried to do is: foreach subfolder in dir_1, take the files that contain the string and move them to the subfolder in dir_2 with the same name. I tried several small modifications of that code, but I cannot get around my mistakes. The main error is "move-item: The given path format is not supported"... any help?
I feel like I could do better but this is my first approach
$dir1 = "C:\temp\data\folder1"
$dir2 = "C:\temp\data\folder2"
$results = Get-ChildItem $dir1 -recurse | Select-String -Pattern "asdf"
$results | ForEach-Object{
$parentFolder = ($_.Path -split "\\")[-2]
Move-Item -Path $_.Path -Destination ([io.path]::combine($dir2,$parentFolder))
}
Select-String can take file paths for its pipeline input. We feed it all the files that are under $dir1 using -recurse to get all of its children in sub folders. $results would contain an array of match objects. One of the properties is the path of the matched file.
With all of those $results we then go though each and extract the parent folder from the path. Then combine that folder with the path $dir2 in order to move it to it destination.
There are several assumptions that we are taking here. Some we could account for if need be. I will mention the one I know could be an issue first.
Your folders should not have any other subfolders under "sub_1, sub_2, ..., sub_n" else they will attempt to move incorrectly. This can be addressed with a little more string manipulation. In an attempt to make the code terse using -Recurse created this caveat.
Here is a one liner that does what you want too:
Get-ChildItem "C:\dir_1" | Where-Object {$_.PSIsContainer -eq $True} | ForEach-Object {$SubDirName = $_.Name;ForEach ($File in $(Get-ChildItem $_.FullName)){If ($File.Name -like "*My-String*"){Move-Item $File.FullName "C:\dir_2\$SubDirName"}}}
And if you'd like to see it broken out like Matt's answer:
$ParentDir = Get-ChildItem "C:\dir_1" | Where-Object {$_.PSIsContainer -eq $True}
ForEach ($SubDir in $ParentDir){
$SubDirName = $SubDir.Name
ForEach ($File in $(Get-ChildItem $SubDir.FullName)){
If ($File.Name -like "*My-String*"){
Move-Item $File.FullName "C:\dir_2\$SubDirName"
}
}
}
I have started learning powershell a couple of days ago, and I couldn't find anything on google that does what I need so please bear with my question.
I have been asked to replace some text strings into multiple files. I do not necessarily know the extension of the possible target files and I don't know their location either. So far I have managed to recursively browse into the directory (get-ChildItem -recurse) and find the string I was looking for with get-content and select-string:
Get-ChildItem -recurse | Get-Content | Select-String -pattern "dummy"
The problem is, I can see the occurences of the text I am looking for, but I don't know how to tell PS to return the path and the name for every matching files as well.
How can I get the name and location of the files that contains the expression I am looking for?
This should give the location of the files that contain your pattern:
Get-ChildItem -Recurse | Select-String "dummy" -List | Select Path
There are a variety of accurate answers here, but here is the most concise code for several different variations. For each variation, the top line shows the full syntax and the bottom shows terse syntax.
Item (2) is a more concise form of the answers from Jon Z and manojlds, while item (1) is equivalent to the answers from vikas368 and buygrush.
List FileInfo objects for all files containing pattern:
Get-ChildItem -Recurse filespec | Where-Object { Select-String pattern $_ -Quiet }
ls -r filespec | ? { sls pattern $_ -q }
List file names for all files containing pattern:
Get-ChildItem -Recurse filespec | Select-String pattern | Select-Object -Unique Path
ls -r filespec | sls pattern | select -u Path
List FileInfo objects for all files not containing pattern:
Get-ChildItem -Recurse filespec | Where-Object { !(Select-String pattern $_ -Quiet) }
ls -r filespec | ? { !(sls pattern $_ -q) }
List file names for all files not containing pattern:
(Get-ChildItem -Recurse filespec | Where-Object { !(Select-String pattern $_ -Quiet) }).FullName
(ls -r filespec | ? { !(sls pattern $_ -q) }).FullName
This is how I would do it, you don't need get-content:
ls -r | Select-String dummy | select line,path
or
ls -r | Select-String dummy | fl *
To see what the different properties are...
This is faster. The second argument is -filter:
ls -r . *.bat | select-string netsh
ls -r -path . -filter *.bat | select-string netsh
This will display the path, filename and the content line it found that matched the pattern.
Get-ChildItem -Path d:\applications\*config -recurse | Select-String -Pattern "dummy"
Pipe the content of your
Get-ChildItem -recurse | Get-Content | Select-String -pattern "dummy"
to fl *
You will see that the path is already being returned as a property of the objects.
IF you want just the path, use select path or select -unique path to remove duplicates:
Get-ChildItem -recurse | Get-Content | Select-String -pattern "dummy" | select -unique path
I modified one of the answers above to give me a bit more information. This spared me a second query later on. It was something like this:
Get-ChildItem `
-Path "C:\data\path" -Filter "Example*.dat" -recurse | `
Select-String -pattern "dummy" | `
Select-Object -Property Path,LineNumber,Line | `
Export-CSV "C:\ResultFile.csv"
I can specify the path and file wildcards with this structures, and it saves the filename, line number and relevant line to an output file.
Get-ChildItem -r | ? {$_.psiscontainer -eq $false} | ? {gc $_.pspath |select-string -pattern "dummy"}
This will give you the full details of all files
To keep the complete file details in resulting array you could use a slight modification of the answer posted by vikas368 (which didn't seem to work well with the ISE autocomplete):
Get-ChildItem -Recurse | Where-Object { $_ | Select-String -Pattern "dummy" }
or in short:
ls -r | ?{ $_ | Select-String -Pattern "dummy" }
If you search into one directory, you can do it:
select-string -Path "c:\temp\*.*" -Pattern "result" -List | select Path
This will display a list of the full path to each file that contains the search string:
foreach ($file in Get-ChildItem | Select-String -pattern "dummy" | Select-Object -Unique path) {$file.path}
Note that it doesn't display a header above the results and doesn't display the lines of text containing the search string. All it tells you is where you can find the files that contain the string.
With PowerShell, go to the path where your files are and then type this command and replace ENTER THE STRING YOU SEARCH HERE (but keep the double quotes):
findstr /S /I /M /C:"ENTER THE STRING YOU SEARCH HERE" *.*
Have a nice day 🙂
