There is a data in my text file. It is a list of IP addresses in column, I want to convert it into csv file and with that also i want to create 3 more columns and put the same data that is present in the first column
so far have created this
$output_file= "D:\output.csv"
#the headers i have given below
Set-Content D:\output.csv 'record,stream,library,thumbnail'
$input_file= "D:\input1.txt"
$lines = Get-Content $input_file
foreach ($line in $lines) {
Add-Content -Path $output_file -Value "$line, $line, $line, $line"
}
Why not go the object way?
$output_file = "D:\output.csv"
$input_file = "D:\input1.txt"
Get-Content -Path $input_file | ForEach-Object {
# output an object
[PsCustomObject]#{
record = $_
stream = $_
library = $_
thumbnail = $_
}
} | Export-Csv -Path $output_file -NoTypeInformation

Having some issues with the syntax. I'm trying to copy the variable value into another csv column.
$file1 = import-csv C:\temp\csv1.csv
$file2 = import-csv C:\Temp\csv2.csv
$file3 = import-csv C:\Temp\csv3.csv
foreach ($line in $file1) {
foreach ($row in $file2) {
if ($line.col1 -eq $row.col1){
#this is the part im having issues with:
$row.col2 = $line.col3 | Export-Csv #???
}
}
}
$row is a reference to an object in $file2. When you update $row, $file2 is automatically updated. Therefore, you can just wait until you have made all your updates before exporting to CSV. So assuming your logic is correct for when you want to update col2 of $file2, you can do the following:
$file1 = import-csv C:\temp\csv1.csv
$file2 = import-csv C:\Temp\csv2.csv
foreach ($line in $file1) {
foreach ($row in $file2) {
if ($line.col1 -eq $row.col1) {
$row.col2 = $line.col3
}
}
}
$file2 | Export-Csv -Path NewFile.Csv -NoType
I am trying to write a script in power shell to read the first column value in excel, find the value in text file and replace that value with value in second column of the excel file.I am new to the power shell. Please help. Below is the code:
$excel = Import-Csv -Path C:\Users\abc\Desktop\newnbc.csv
foreach ($ex in $excel)
{
$name = $ex.first
$match = Get-Content -Path 'C:\Users\abc\Desktop\all.txt'
foreach ($ma in $match)
{
if ($match | %{$_ -replace $ex.first,$ex.last})
{
((Get-Content -Path C:\Users\abc\Desktop\all.txt -Raw) -replace $name,$ex.last) | Set-Content -Path C:\Users\abc\Desktop\all.txt
}
}
}
Judging by the info from your comment, it looks like the input CSV is a space-delimited file, something like this:
first last
i3-chq-nbc-dt-comcleanup-cmd i3-chq-nbc-dt-d-com-cleanup
Of course, if the delimiter character is something other than a space, change the value for the -Delimiter parameter.
$fileName = 'C:\Users\abc\Desktop\all.txt'
# get the original content of the text file BEFORE the loop
$content = Get-Content -Path $fileName -Raw
# then, import the csv with the replacement strings and start replacing the content
Import-Csv -Path 'C:\Users\abc\Desktop\newnbc.csv' -Delimiter ' ' | ForEach-Object {
$content = $content -replace $_.first, $_.last
}
# finally, save the updated content to file
$content | Set-Content -Path $fileName
Working on a code which will replace a set of characters from a text files in a folder. IS there a way where it can do it for all the files in the folder. I am using a Windows 7 OS and Powershell Version 3.Attaching the code which I have. The issue is it creates a new file when I run the code (New_NOV_1995.txt) but it doesn't change any character in the new file as mentioned in the code. Help very much Appreciated.
$lookupTable = #{
'¿' = '|'
'Ù' = '|'
'À' = '|'
'Ú' = '|'
'³' = '|'
'Ä' = '-'
}
$original_file = 'C:\FilePath\NOV_1995.txt'
$destination_file = 'C:\FilePath\NOV_1995_NEW.txt'
Get-Content -Path $original_file | ForEach-Object {
$line = $_
$lookupTable.GetEnumerator() | ForEach-Object {
if ($line -match $_.Key)
{
$line = $line -replace $_.Key, $_.Value
}
}
$line
} | Set-Content -Path $destination_file
In the following example, I'm assuming that H:\Replace_String is a directory. In your code above, you don't have a backslash so it would only select files in the root of H:.
$configFiles = Get-ChildItem -path H:\Replace_String\*.txt
foreach ($file in $configFiles)
{
(Get-Content $file) |
Foreach-Object { $_ -replace "Cat", "New_Cat" } |
Foreach-Object { $_ -replace "Dog", "New_Dog" } |
Set-Content $file
}
The (original) answer proposed by Tony Hinkle needs another loop. The reason for this is that Get-Content produces an array. Each line represents an element of the array.
$configFiles = Get-ChildItem -path 'H:\Replace_String\*.txt'
foreach ($file in $configFiles){
$output = #()
$content = Get-Content $file
foreach ($line in $content) {
$line = $content.Replace("Cat", "New_Cat")
$line = $content.Replace("Dog", "New_Dog")
$output += $line
}
$output | Set-Content -Path $file
}
Edit: I noticed that Tony Hinkle's answer was modified as I posted this. He's sending everything through a pipeline where I'm storing the array in a variable then looping through. The pipeline method is probably more memory efficient. The variable with second loop for each element of the array is more easily modified to do more than just the two replacments.
I have files which need to be modified according to mapping provided in CSV. I want to read each line of my txt file and depending if specified value exist I want to replace other strings in that line according to my CSV file (mapping). For that purpose I have used HashTable. Here is my ps script:
$file ="path\map.csv"
$mapping = Import-CSV $file -Encoding UTF8 -Delimiter ";"
$table = $mapping | Group-Object -AsHashTable -AsString -Property Name
$original_file = "path\input.txt"
$destination_file = "path\output.txt"
$content = Get-Content $original_file
foreach ($line in $content){
foreach ($e in $table.GetEnumerator()) {
if ($line -like "$($e.Name)") {
$line = $line -replace $e.Values.old_category, $e.Values.new_category
$line = $line -replace $e.Values.old_type, $e.Values.new_type
}
}
}
Set-Content -Path $destination_file -Value $content
My map.csv looks as follows:
Name;new_category;new_type;old_category;old_type
alfa;new_category1;new_type1;old_category1;old_type1
beta;new_category2;new_type2;old_category2;old_type2
gamma;new_category3;new_type3;old_category3;old_type3
And my input.txt content is:
bla bla "bla"
buuu buuu 123456 "test"
"gamma" "old_category3" "old_type3"
alfa
When I run this script it creates exactly the same output as initial file. Can someone tell me why it didn't change the line where "gamma" appears according to my mapping ?
Thanks in advance
Couple of things to change.
Firstly there is no need to change $mapping to a hash, Import-Csv already gives you an object array to work with.
Secondly, if you want to update the elements of $content, you need to use a for loop such that you can directly access modify them. Using a foreach creates a new variable in the pipeline and you were previously modifying it but then never writing it back to $content
Below should work:
$file ="map.csv"
$mapping = Import-CSV $file -Encoding UTF8 -Delimiter ";"
$original_file = "input.txt"
$destination_file = "output.txt"
$content = Get-Content $original_file
for($i=0; $i -lt $content.length; $i++) {
foreach($map in $mapping) {
if ($content[$i] -like "*$($map.Name)*") {
$content[$i] = $content[$i] -replace $map.old_category, $map.new_category
$content[$i] = $content[$i] -replace $map.old_type, $map.new_type
}
}
}
Set-Content -Path $destination_file -Value $content
I have 2 csv files and need to create a 3rd.
csv_1 (only 1 column)
USERNAME
guy1
guy2
guy3
csv_2
"ID","USERNAME","GROUPU"
"1","guyA","Default"
"2","guy1","Default"
"3","guyB","Default"
"4","guy3","Default"
"5","guyC","Default"
for an output from comparing these two tables I'd like to see:
USERNAME,ID
guy1,2
guy3,4
I tried this and it dumped far too much data (listing all entries multiple times)
$file1 = Import-Csv csv_1.csv
$file2 = Import-Csv csv_2.csv
foreach ($line in $file1){
$U1 = $line.User
foreach ($line in $file2)
$U2 = $line.USERNAME
$I2 = $line.ID
If ($U1 = $U2){
$x = $U2+","+$I2
ac temp.csv$x
}
}
}
I added a break:outside line after the ac temp.csv $x line but then it only listed 1 entry multiple times.
I also tries this (based on this entry):
$file1 = Import-Csv csv_1.csv
$file2 = Import-Csv csv_2.csv
ForEach($Record in $file1){
$MatchedValue = (Compare-Object $file2 $Record -Property "USERNAME" -IncludeEqual -ExcludeDifferent -PassThru).value
$Record = Add-Member -InputObject $Record -Type NoteProperty -Name "SQLID" -Value $MatchedValue
}
$file1 #|Export-Csv ".\Combined.csv" -NoTypeInformation
but didn't get anything in the SQLID column and it included some values in $file1 that are not in $file2. I figure the lack of SQLID value is because I need to add a variable there (the -value just being $matchedValue which is just the line from $file1), but I'm not sure how to get the variable from the correct record in $file2.
Suggestions?
For each entry in $file1, test if an entry in $file2 has the same USERNAME property value. If so, select the USERNAME and ID Properties and add the entry to a collection that you can write back to the final csv file:
$file1 = Import-Csv .\csv_1.csv
$file2 = Import-Csv .\csv_2.csv
$users = #()
foreach($u in $file1)
{
$u2 = $file2 |Where-Object {$_.USERNAME -eq $u.USERNAME}|Select USERNAME,ID -First 1
if($u2)
{ $users += $u2 }
}
$users|Export-Csv -Path .\csv_3.csv -NoTypeInformation -Force
