$web = Get-SPWeb http://mysite
ForEach($list in $web.Lists)
{
if($list.BaseType -eq "DocumentLibrary")
{
Write-Host $list.Fields
if($list.Fields.ContainsField("marking") -eq $true)
{
Write-Host "found" $list.Title
}

} | Out-File test.txt
I have this code, which doesn't work due to write-host outputting to command line so obviously it won't write to the file.
How can I make it so it doesn't output to the command line but just outputs all the items found to the text file
Place your Out-File with the -Append switch after the lines you want to write, and take out theWrite-Host.
This would be a cleaner way to do it and probably faster. You're not going to get the carriage
return you're getting in your script after $list.Fields but I suspect you don't want that anyway
$doclibraries = (Get-SPWeb http://mysite).Lists | where {$_.BaseType -eq 'DocumentLibrary'}
foreach ($library in $doclibraries) {
$line = $library.Fields
if ($Line.ContainsField('marking')) {
Add-Content -Value "$line found $($library.title)" -Path test.txt
}
}

I found a little script to get all the local groups and members and it's working perfectly but I need to write the output on PowerShell.
Trap {"Error: $_"; Break;}
function EnumLocalGroup($LocalGroup) {
$Group = [ADSI]"WinNT://$strComputer/$LocalGroup,group"
"`r`n" + "Group: $LocalGroup"
$Members = #($Group.psbase.Invoke("Members"))
foreach ($Member In $Members) {
$Name = $Member.GetType().InvokeMember("Name", 'GetProperty', $Null, $Member, $Null)
$Name
}
}
$strComputer = gc env:computername
"Computer: $strComputer"
$computer = [adsi]"WinNT://$strComputer"
$objCount = ($computer.PSBase.Children | Measure-Object).Count
$i = 0
foreach ($adsiObj in $computer.PSBase.Children) {
switch -regex ($adsiObj.PSBase.SchemaClassName) {
"group" {
$group = $adsiObj.Name
EnumLocalGroup $group
}
}
$i++
}
I already tried this:
function EnumLocalGroup($LocalGroup) | Out-File -FilePath "E:\PS\Malik\group.txt"
But the code won't start if I do that. I also tried to use this whole Out-File line at the end of the code after the } but doesn't work either and this is the only solution I find on Internet.
If you want to incorporate logging into a function you need to put it into the function body, e.g.
function EnumLocalGroup($LocalGroup) {
....
$foo = 'something'
$foo # output returned by function
$foo | Add-Content 'log.txt' # output to log file
...
}
or
function EnumLocalGroup($LocalGroup) {
...
$foo = 'something'
$foo | Tee-Object 'log.txt' -Append # output goes to log file and StdOut
...
}
Otherwise you have to do the logging when you call the function:
EnumLocalGroup $group | Add-Content 'C:\log.txt'
I have a script that scans for a specific folder in users AppData folder. If it finds the folder, it then returns the path to a txt file. So we can see the computer name and username where it was found.
I would like to be able to format the what is actually written to the text file, so it removes everything from the path except the Computer and User names.
Script:
foreach($computer in $computers){
$BetterNet = "\\$computer\c$\users\*\AppData\Local\Google\Chrome\User Data\Default\Extensions\gjknjjomckknofjidppipffbpoekiipm"
Get-ChildItem $BetterNet | ForEach-Object {
$count++
$betternetCount++
write-host BetterNet found on: $computer
Add-Content "\\SERVERNAME\PowershellScans\$date\$time\BetterNet.txt" $_`n
write-host
}
}
The text files contain information like this
\\computer-11-1004S10\c$\users\turtle\AppData\Local\Google\Chrome\User Data\Default\Extensions\gjknjjomckknofjidppipffbpoekiipm
\\computer-1004-24S\c$\users\camel\AppData\Local\Google\Chrome\User Data\Default\Extensions\gjknjjomckknofjidppipffbpoekiipm
\\computer-1004-23S\c$\users\rabbit\AppData\Local\Google\Chrome\User Data\Default\Extensions\gjknjjomckknofjidppipffbpoekiipm
If you have each line in a form of the string $string_containing_path then it is easy to split using split method and then add index(1) and (4) that you need:
$afterSplit = $string_containing_path.Split('\')
$stringThatYouNeed = $afterSplit[1] + " " + $afterSplit[4]
You can also use simple script that will fix your current logs:
$path_in = "C:\temp\list.txt"
$path_out= "C:\temp\output.txt"
$reader = [System.IO.File]::OpenText($path_in)
try {
while($true){
$line = $reader.ReadLine()
if ($line -eq $null) { break }
$line_after_split_method = $line.Split('\')
$stringToOutput = $line_after_split_method[1] + " " + $line_after_split_method[4] + "`r`n"
add-content $path_out $stringToOutput
}
add-content $path_out "End"
}
finally {
$reader.Close()
}
If you split your loop into two foreach loops, one for computer and user directory it would be easier to output the name of the user directory.
$output = foreach($computer in $computers){
$UserDirectories = Get-ChildItem "\\$computer\c$\users\" -Directory
foreach ($Directory in $UserDirectories) {
$BetterNet = Get-ChildItem (Join-Path $Directory.fullname "\AppData\Local\Google\Chrome\User Data\Default\Extensions\gjknjjomckknofjidppipffbpoekiipm")
Add-Content "\\SERVERNAME\PowershellScans\$date\$time\BetterNet.txt" "$computer $($Directory.name)`r`n"
write-host BetterNet found on: $computer
$BetterNet
}
}
$output.count
Guys i'm having some issues converting my Perl script to powershell, I need some help. In the host file of our machines, we have all of the URL's to our test environments blocked. In my PERL script, based on which environment is selected, it will comment out the line of the environment selected to allow access and block others so the testers can't mistakenly do things in the wrong environment.
I need help converting to powershell
Below is what I have in PERL:
sub editHosts {
print "Editing hosts file...\n";
my $file = 'C:\\Windows\\System32\\Drivers\\etc\\hosts';
my $data = readFile($file);
my #lines = split /\n/, $data;
my $row = '1';
open (FILE, ">$file") or die "Cannot open $file\n";
foreach my $line (#lines) {
if ($line =~ m/$web/) {
print FILE '#'."$line\n"; }
else {
if ($row > '21') {
$line =~ s/^\#*127\.0\.0\.1/127\.0\.0\.1/;
$line =~ s/[#;].*$//s; }
print FILE "$line\n"; }
$row++;
}
close(FILE);
}
Here is what i've tried in Powershell:
foreach ($line in get-content "C:\windows\system32\drivers\etc\hosts") {
if ($line -contains $web) {
$line + "#"
}
I've tried variation including set-content with what used to be in the host file, etc.
Any help would be appreciated!
Thanks,
Grant
-contains is a "set" operator, not a substring operator. Try .Contains() or -like.
This will comment out lines matching the variable $word, while removing # from non-matches (except the header):
function Edit-Hosts ([string]$Web, $File = "C:\windows\system32\drivers\etc\hosts") {
#If file exists and $web is not empty/whitespace
if((Test-Path -Path $file -PathType Leaf) -and $web.Trim()) {
$row = 1
(Get-Content -Path $file) | ForEach-Object {
if($_ -like "*$web*") {
#Matched PROD, comment out line
"#$($_)"
} else {
#No match. If past header = remove comment
if($row -gt 21) { $_ -replace '^#' } else { $_ }
}
$row++
} | Set-Content -Path $file
} else {
Write-Error -Category InvalidArgument -Message "'$file' doesn't exist or Web-parameter is empty"
}
}
Usage:
Edit-Hosts -Web "PROD"
This is a similar answer to Frode F.'s answer, but I'm not yet able to comment to add my 2c worth, so have to provide an alternative answer instead.
It looks like one of the gotchas moving from perl to PowerShell, in this example, is that when we get the content of the file using Get-Content it is an "offline" copy, i.e. any edits are not made directly to the file itself. One approach is to compile the new content to the whole file and then write that back to disk.
I suppose that the print FILE "some text\n"; construct in perl might be similar to "some text" | Out-File $filename -Encoding ascii -Append in PowerShell, albeit you would use the latter either (1) to write line-by-line to a new/empty file or (2) accept that you are appending to existing content.
Two other things about editing the hosts file:
Be sure to make sure that your hosts file is ASCII encoded; I have caused a major outage for a key enterprise application (50k+ users) in learning that...
You may need to remember to run your PowerShell / PowerShell ISE by right-clicking and choosing Run as Administrator else you might not be able to modify the file.
Anyway, here's a version of the previous answer using Out-File:
$FileName = "C:\windows\system32\drivers\etc\hosts"
$web = "PROD"
# Get "offline" copy of file contents
$FileContent = Get-Content $FileName
# The following creates an empty file and returns a file
# object (type [System.IO.FileInfo])
$EmptyFile = New-Item -Path $FileName -ItemType File -Force
foreach($Line in $FileContent) {
if($Line -match "$web") {
"# $Line" | Out-File $EmptyFile -Append -Encoding ascii
} else {
"$Line" | Out-File $EmptyFile -Append -Encoding ascii
}
}
Edit
The ($Line -match "$web") takes whatever is in the $web variable and treats it as a regular expression. In my example I was assuming that you were just wanting to match a simple text string, but you might well be trying to match an IP address, etc. You have a couple of options:
Use ($Line -like "*$web*") instead.
Convert what is in $web to be an escaped regex, i.e. one that will match literally. Do this with ($Line -match [Regex]::Escape($web)).
You also wanted to strip off comments from any line past row 21 of the hosts file, should that line not match $web. In perl you have used the s substitution operator; the PowerShell equivalent is -replace.
So... here is an updated version of that foreach loop:
$LineCount = 1
foreach($Line in $FileContent) {
if($Line -match [Regex]::Escape($web) {
# ADD comment to any matched line
$Line = "#" + $Line
} elseif($LineCount -gt 21) {
# Uncomment the other lines
$Line = $Line -replace '^[# ]+',''
}
# Remove 'stacked up' comment characters, if any
$Line = $Line -replace '[#]+','#'
$Line | Out-File $EmptyFile -Append -Encoding ascii
$LineCount++
}

If you wanted to verify what was in there and then add entries, you could use the below which is designed to be ran interactively and returns any existing entries you specify in the varibles:
Note: the `t is powershell's in script method for 'Tab' command.
$hostscontent
# Script to Verify and Add Host File Entries
$hostfile = gc 'C:\Windows\System32\drivers\etc\hosts'
$hostscontent1 = $hostfile | select-string "autodiscover.XXX.co.uk"
$hostscontent2 = $hostfile | select-string "webmail.XXX.co.uk"
$1 = "XX.XX.XXX.XX`tautodiscover.XXX.co.uk"
$2 = "webmail.XXX.co.uk"
# Replace this machines path with a path to your list of machines e.g. $machines = gc \\machine\machines.txt
$machines = gc 'c:\mytestmachine.txt'
ForEach ($machine in $machines) {
If ($hostscontent1 -ne $null) {
Start-Sleep -Seconds 1
Write-Host "$machine Already has Entry $1" -ForegroundColor Green
} Else {
Write-Host "Adding Entry $1 for $machine" -ForegroundColor Green
Start-Sleep -Seconds 1
Add-Content -Path C:\Windows\System32\drivers\etc\hosts -Value "XX.XX.XXX.XX`tautodiscover.XXX.co.uk" -Force
}
If ($hostscontent2 -ne $null) {
Start-Sleep -Seconds 1
Write-Host "$machine Already has Entry $2" -ForegroundColor Green
} Else {
Write-Host "Adding Entry $2 for $machine" -ForegroundColor Green
Start-Sleep -Seconds 1
Add-Content -Path C:\Windows\System32\drivers\etc\hosts -Value "XX.XX.XXX.XX`twebmail.XXX.co.uk" -Force
}
}
I am trying to find a string in the hosts files of computers in a text file. I want to check each machine in the text file for the change in the hosts file.
For security purposes, I cannot put the actual string I am searching for. I am very new to PowerShell, and I tried to do this in CMD, but I could not get the output I wanted.
$sys = Get-Content .\Systems.txt
$Loc = "\\$sys\c$\Windows\System32\Drivers\etc\hosts"
$SearchStr = "string"
$sel = Select-String -pattern $SearchStr -path $Loc
ForEach ($System in $sys) {
If ($sel -eq $null)
{
write-host $sys NotFound
}
Else
{
write-host $sys Found
}
}
You weren't too far off, you just needed to re-think your ForEach loop a little. Move your $Loc = line within the loop so that it updates for each system, then skip the $sel = line and just put that in your If check and you're all set:
$sys = Get-Content .\Systems.txt
$SearchStr = "string"
ForEach ($System in $sys) {
$Loc = "\\$system\c`$\Windows\System32\Drivers\etc\hosts"
If (Select-String -pattern $SearchStr -path $Loc -Quiet)
{
write-host "$system Found"
}
Else
{
write-host "$system Not Found"
}
}
I also escaped the dollar sign in the path for c$. I don't think it's needed in this case, but it's good practice in general when using dollar signs that you want to actually be used as such in strings like that.
I have wrote the following script to read the CSV file to perform the custom format of output.
Script is below:
$Content = Import-Csv Alert.csv
foreach ($Data in $Content) {
$First = $Data.DisplayName
$Second = $Data.ComputerName
$Third = $Data.Description
$Four = $Data.Name
$Five = $Data.ModifiedBy
$Six = $Data.State
$Seven = $Data.Sev
$Eight = $Data.Id
$Nine = $Data.Time
Write-Host "START;"
Write-Host "my_object="`'$First`'`;
Write-Host "my_host="`'$Second`'`;
Write-Host "my_long_msg="`'$Third`'`;
Write-Host "my_tool_id="`'$Four`'`;
Write-Host "my_owner="`'$Five`'`;
Write-Host "my_parameter="`'$Four`'`;
Write-Host "my_parameter_value="`'$Six`'`;
Write-Host "my_tool_sev="`'$Seven`'`;
Write-Host "my_tool_key="`'$Eight`'`;
Write-Host "msg="`'$Four`'`;
Write-Host "END"
}
The above script executing without any error.
Tried with Out-File and redirection operator in PowerShell to dump the output into a file, but I'm not finding any solution.
Write-Host writes to the console. That output cannot be redirected unless you run the code in another process. Either remove Write-Host entirely or replace it with Write-Output, so that the messages are written to the Success output stream.
Using a foreach loop also requires additional measures, because that loop type doesn't support pipelining. Either run it in a subexpression:
(foreach ($Data in $Content) { ... }) | Out-File ...
or assign its output to a variable:
$output = foreach ($Data in $Content) { ... }
$output | Out-File ...
Another option would be replacing the foreach loop with a ForEach-Object loop, which supports pipelining:
$Content | ForEach-Object {
$First = $_.DisplayName
$Second = $_.ComputerName
...
} | Out-File ...
Don't use Out-File inside the loop, because repeatedly opening the file will perform poorly.
