Powershell text search tool

Powershell text search tool

Text search tool in Powershell

Wrote a quick search tool for Windows that uses some cmdlets from Powershell to search through txt-files,finds certain key words and writes them in a easily readable format inside a potentially user defined outfile. (github)

The tool ask for the file being searched for and the word that the user wants to search these files for.



# Before execution navigate to folder where you are searching through


Function searchthrough




# defines the output file name. This version creates the file in same folder. Change name and path if necessary

$outputFile = "userbasedscanthrough.log"


# Checks if file already exists in folder and removes it

if(Test-Path $outputFile){

# User confirms deletion

$confirmbool = Read-Host -Prompt "Poistetaanko $outputFile (Y/N): "

while (Test-Path $outputFile){

# Check if user wants to delete old file or rename file and make the output file have a new name

if($confirmbool -eq "Y" -Or $confirmbool -eq "y"){

Remove-Item $outputFile


# Asks for new filename

elseif ($confirmbool -eq "N" -Or $confirmbool -eq "n") {

$othername = Read-Host -Prompt "Anna tiedostolle toinen nimi: "

$outputFile = $othername


# Keeps the user in the loop so the program doesn't throw unnecessary errors.

# The error message here tells the user to select either y or n


Write-Error "Ei kelpaa valitse joko Y tai N"

$confirmbool = Read-Host -Prompt "Poistetaanko $outputFile (Y/N): "




# What to search for, First one asks for the file name or type eg. log, .txt etc...

$whatfiles = Read-Host -Prompt "Mitä tiedostoa etsitään: "

# Searches for a specific word from the file

# do-while function makes it so the user can't search for an empty "word"

do {

$keyWord = Read-Host -Prompt "Mitä sanaa etsitään tiedostoista: "

if($keyWord -eq ""){

Write-Output "Ei voi olla tyhjä"


}while($keyword -eq "")

# What name the file has.

Write-Output "Katso $outputFile"

# Write to the new file

Foreach ($kw in $keyWord)


# Select new match

Get-Childitem -Filter *$whatfiles* -Recurse -Exclude *.doc* |

Select-String -Pattern "$kw" |

# What was searched, the line that was found, on which line this can be found, and path to file

Select Path, @{n='KeyWord';e={ $kw }}, LineNumber, line |


# Output file alter name @ the $outputfile variable to get different files

Out-File .\$outputfile
