INI file parsing in PowerShell
(8 answers)
Closed 5 years ago.
(I've reviewed the other answers but didn't find it match my question)
I have an INI file that looks like that:
[DATA]
installerDir=C:\installerDir
scriptsDir=C:\Scripts
TargetDirName=MSI
[DB]
DB_Name="Database_2211"
DistribDir=DataDist
TargetDir=TarMSI
I want to get as an output 2 files that will look like that:
First file will contain the following data:
installerDir=C:\installerDir
scriptsDir=C:\Scripts
TargetDirName=MSI
Second file will contain the following data:
DB_Name="Database_2211"
DistribDir=DataDist
TargetDir=TarMSI
Files names should be something_DATA.ini & something_DB.ini accordingly.
Files content should not include the block name (i.e.: DATA -or- DB...)
I found that code for bash but cannot find it for PowerShell.
You could do this:
$Ini = Get-Content 'Something.ini'
$Split = $Ini -Replace '\[DATA\]' -Split '\[DB\]'
$Split[0].Trim() | Out-file 'something_DATA.ini'
$Split[1].Trim() | Out-file 'something_DB.ini'
Explanation:
Reads the contents of the .ini file with Get-Content
Replaces the [DATA] text part with blank (to remove it) and splits the content based on the [DB] part (which is also removes it)
Removes blank lines from each part of the split (accessing them with their array index [0] and [1]) and redirects them to the files.

I have a source file which is in .txt format. It looks like a semi-colon separated file:
100;200;ThisisastringcolumnA;4;
101;400;Thisisastringc;lumnA;5;
102;600;ThisisastringcolumnB;6;
104;600;Thisisa;;ringcolumnB;6;
However, it is determined by length. So it is a length-delimited file.
Fist column for example is from first value to the third (100), then a semi-colon follows.
Second column starts at 5th position (including), until (including) 7th position. A string column can contain a semi-colon.
Now I want to import this length-delimited txt file with Powershell and export it as a csv file. This file should be really semi-colon separated. The result should look like
100;200;ThisisastringcolumnA;4;
101;400;"Thisisastringc;lumnA";5;
102;600;ThisisastringcolumnB;6;
104;600;"Thisisa;;ringcolumnB";6;
But I have simply no idea how to do it? I googled it, but I did not find that much useful code examples for importing length-delimited txt files with PowerShell.
Unfortunately, I cannot use Python. I am not sure, if this task is generally possible using Powershell? Because when exporting, Powershell also needs to recognize that there are string values containing the separator, so it has to pay attention to the quoting: "Thisisa;;ringcolumnB". I think it would be also ok for me, if the whole column is quoted, so every entry in a string column gets quotes added.
You can use regex to describe a string in which the 3rd "column" contains a ; and then inject the quotation marks with the -replace operator:
$lines = Get-Content path\to\file.txt
#($lines) -replace '(.{3});(.{3});(.{20}(?<=;.{0,19}));(.);', '$1;$2;"$3";$4;'
The expression (.{20}(?<=;.{0,19})) is going to match the 20-char 3rd column value only if it contains at least one semi-colon - so lines with no semicolon in that column will be left alone:
# let's try it out with your test data
$lines = #'
100;200;ThisisastringcolumnA;4;
101;400;Thisisastringc;lumnA;5;
102;600;ThisisastringcolumnB;6;
104;600;Thisisa;;ringcolumnB;6;
'# -split '\r?\n'
#($lines) -replace '(.{3});(.{3});(.{20}(?<=;.{0,19}));(.);', '$1;$2;"$3";$4;'
Which yields the following four strings:
100;200;ThisisastringcolumnA;4;
101;400;"Thisisastringc;lumnA";5;
102;600;ThisisastringcolumnB;6;
104;600;"Thisisa;;ringcolumnB";6;
To write the output back to file, use Set-Content:
#($lines) -replace '(.{3});(.{3});(.{20}(?<=;.{0,19}));(.);', '$1;$2;"$3";$4;' |Set-Content path\to\fixed_output.scsv

Export-CSV exports length but not name

Operating System - Windows 10
Powershell version - 5.1.15063.1088
Ok, I'm really trying hard to think logically what can be wrong with this PowerShell script, but apparently can't get an idea and asking for some help. So here is what I'm trying to do, simple as 1+1
If I understood the tutorial correctly, creating an array in PowerShell is like this:
$someVariable = "PowerShell", "MowerShell", "HowerShell", "ZowerShell"
Then I'm simply trying to write this thing to csv file with comma as delimeter, but firstly give it a try in the console output
$someVariable | ConvertTo-Csv -NoTypeInformation
According to PowerShell 5.1 official documentation
...Specifies a delimiter to separate the property values. The default
is a comma (,).
So no additional writing that I would like to use comma as delimiter is not required. Once the command Write-Host $someVariable is executed, I see this weird output:
"Length" "10" "10" "10" "10"
What is this? Am I suppose to see the values of my variable separated with simple comma? So from the numbers I can guess that scripts calculates the amount of alphabet letters in each word -
P o w e r S h e l l
contains 10 letters.
Is this the suggested way to calculate the amount of letters in the string (in case I get PowerShell task on my next job interview) using ConvertTo-Csv command?
Writing this funky data to the csv file itself leads to more unexpected results:
Now I'm completely lost what those numbers are...
Is this possible to write my strings as STRINGS to the csv file in one line rather then silly numbers?
The desired output is this entry as headers in the csv file:
"PowerShell","MowerShell","HowerShell","ZowerShell"
The output reads "Length", and has a series of 10's. Each of your strings are 10 characters long (the double quotes aren't factored in).
Length can be calculated many ways. I wouldn't say there is one suggested way, only the ways that fit what you're trying to do.
To get the literal text of what you posted (no headers, etc.) in a csv, try:
$someVariable | Out-File foo.csv

Get only filename from full path of a file
(2 answers)
Closed 5 years ago.
I'm writing a PowerShell script to output the process,
$Process=chknull $_.Properties[0].Value
$Process_new=$Process -replace '(?<! .*) ','_'
The above code outputs the result as entire path of process, Eg:
C:\Windows\System32\Notepad.exe.
Is there a way, where I can get just "Notepad.exe"
If you're getting a full path return like that as a string you can set the value into a variable and then use split on it and grab the last entry in the resulting array.
Example:
("C:\Windows\System32\Notepad.exe." -split "\\")[-1]
Remember to use two "\" as it is also an escape character in regex.
([IO.FileInfo]"C:\Windows\System32\Notepad.exe").Name

Import Variables from Text File in Powershell
(1 answer)
Closed 6 years ago.
Lets say I have a text file full of variables.
I would like to create a separate file in which I can read and call these variables using powershell.
EX. Variable.txt contains $X=10
Main.ps1 retrieves the variable X from the text file, and doubles it.
Apologize is this is an amateur question, I am very new to powershell.
For your specific purpose, you could have a file, data.ps1 containing your data, like so:
$x=10
Then, a script.ps1 file, similar to the following:
. ./data.ps1
$x = $x * 2
Write-Host "Value X is $x"
Which would give you the following output when you run ./script.ps1:
Value X is 20
I'm just wondering if it's possible to read the content of text file with specific index?
What I mean is like this, for example:
I have text file like this, 'test1.txt'
12345678900 ## ## readthistext
54321123440 ## ## hellothistext
I just want to read the content of text file after of the hashtag.
To read the text after the # characters you must read the file content up to the # characters first. Also, in PowerShell you normally read files either line by line (via Get-Content) or completely (via Get-Content -Raw). You can discard those parts of the read content that don't interest you, though. For instance:
(Get-Content 'C:\input.txt') -replace '^.*#'
The above will read the file C:\input.txt and for each line remove the text from the beginning of the line up to the last # character.
