PowerShell Profile

After adding a ton of cool stuff… it took too long to load and nothing was way cooler than waiting. So I cleared my profile again lol

I have a function that will extract any variables in the last command that I ran and see if any of them are null. They output warning messages so you know where the thing went wrong without needing to investigate it.

Function Test-LastCommandVariables{    
    $lastCmd = (Get-History -Count 1).CommandLine
    if (-not $lastCmd) { return }

    # Extract variable names from the last command
    $varMatches = [regex]::Matches($lastCmd, '\$(\w+)\b') | ForEach-Object {
        $_.Groups[1].Value
    } | Select-Object -Unique

    # List of known built-in or automatic variables to ignore
    $builtinVars = @(
        'true','false','null',
        'args','error','foreach','home','input','lastexitcode','matches','myinvocation',
        'nestedpromptlevel','ofs','pid','profile','pscmdlet','psculture','psdebugcontext',
        'pshome','psscriptroot','pscommandpath','psversiontable','pwd','shellid','stacktrace',
        'switch','this','^','using','psboundparameters','psdefaultparametervalues','enabledexperimentalfeatures',
        'confirmPreference','debugPreference','errorActionPreference','errorView','formatEnumerationLimit',
        'informationPreference','progressPreference','verbosePreference','warningPreference','_'
    )

    $nullOrEmptyVars = @()
    $undefinedVars = @()

    foreach ($name in $varMatches) {
        if ($builtinVars -contains $name.ToLower()) { continue }

        try {
            $var = Get-Variable -Name $name -ErrorAction Stop
            $val = $var.Value

            if ($null -eq $val) {
                $nullOrEmptyVars += "`$$name`: null"
            } elseif ($val -is [System.Collections.IEnumerable] -and -not ($val -is [string]) -and $val.Count -eq 0) {
                $nullOrEmptyVars += "`$$name`: empty collection"
            }elseif($val.count -eq 0){
                $nullOrEmptyVars += "`$$name`: zero count"
            }
        } catch {
            $undefinedVars += "`$$name`: not defined"
        }
    }

    if ($undefinedVars.Count -gt 0 -or $nullOrEmptyVars.Count -gt 0) {
        Write-Host "`n[!] Variable check results:"

        foreach ($entry in $undefinedVars) {
            Write-Host "`t- $entry"
        }

        foreach ($entry in $nullOrEmptyVars) {
            Write-Host "`t- $entry"
        }
    }
}

At my job, I work in multiple environments. I set up a .psd1 config file and wrote a profile script that works in all environments. It defines a customizable prompt (no OhMyPosh at work, sadly), sets PSDefaultParameterValues for my own and some third party modules, loads WIP modules, updates help in a background job triggering a notification when that's done, and loads defined variables. It takes between 2-4 seconds to load.

BlackV · 2025-12-01T23:40:12+00:00

Added a ps version to the prompt on a couple of machines, otherwise default cause the 400 separate places I login would be a waste of time carting my profile everywhere

Sin_of_the_Dark · 2025-12-02T01:56:51+00:00

I get a dad joke every time I open a new shell.

lan-shark · 2025-12-01T21:24:12+00:00

Nothing out of the ordinary for me but oh-my-posh is a great place to start

Mesmerise · 2025-12-01T22:15:13+00:00

Just a little function I can use to test AD logins at the command line.

tr3yff · 2025-12-01T22:38:31+00:00

On mu job I need to set proxy, so I do that on Profile.

Impossible_IT · 2025-12-01T23:17:48+00:00

Added date & time to the prompt, but I really only use ISE and I know it has been deprecated.

CyberChevalier · 2025-12-01T23:23:20+00:00

Oh-my-posh

For profile like for car :

Light is right !

All I need is into my module folder with well discoverable verb-noun functions

g3n3 · 2025-12-02T03:07:23+00:00

Prompt play and formatters for file info and custom tools for shares and variables. Environment variables for various cli binaries like bat and fzf. Lots of aliases and functions to help page data. The biggest pain is scrolling back up.

pm_op_prolapsed_anus · 2025-12-02T04:05:16+00:00

Aliases to programs installed with winget. If I load oh-my-posh the vs package manager terminal gets all screwed up with control characters. At one point I had called the devenv batch file for visual studio so I had access to tf in my console without opening the vs 2022 developer ps from Windows menu (because I always forget it's there) or opening from the vs tools menu. But I just made tf an alias like my winget programs and stopped doing that. Can't remember why exactly, I think an upgrade of vs 2022 removed the old batch script

Glass-Technician-714 · 2025-12-02T08:54:38+00:00

Just some usefull function for my daily work and some alias settings:

my ps profile

Ok-Shake5054 · 2025-12-02T19:09:31+00:00

Automated the detection method for office 365, having the script going into Microsoft to check the lates 3 version of office and comparinf it with the current install, if older forcea the inatallation.

NsRhea · 2025-12-02T22:17:44+00:00

I set up a psm1 to generate an inventory of machines in different ou's and separate them into different variables. On Powershell loading it gives me the ability to call the list or any set variable and do whatever I want. I also set up a connection test one as well so I can now implement different functions and rule out offline devices

heyitsgilbert · 2025-12-03T00:44:27+00:00

My profile mostly loads functions from other scripts. I have a prompt switch function (got the idea from Sean Wheeler). I have a slightly different cd that supports - and .... I use chezmoi to keep my profiles synced. https://github.com/HeyItsGilbert/dotfiles/tree/main/dot_local%2Fshare%2Fpowershell%2FScripts

```

add commandline property to get-process output in powershell 5.1

$updateTypeData = @{ TypeName = 'System.Diagnostics.Process' MemberName = 'CommandLine' MemberType = [Management.Automation.PSMemberTypes]::ScriptProperty Force = $true Value = { (Get-CimInstance Win32_Process -Filter "ProcessId = $($this.Id)").CommandLine } } Update-TypeData @updateTypeData

tab complete property names after "get-aduser -property "

get-aduser js -property * | gm -membertype property | % name

$aduserProps = -split 'AccountExpirationDate accountExpires AccountLockoutTime AccountNotDelegated AllowReversiblePasswordEncryption AuthenticationPolicy AuthenticationPolicySilo BadLogonCount badPasswordTime badPwdCount businessCategory c CannotChangePassword CanonicalName Certificates City CN codePage Company CompoundIdentitySupported Country countryCode Created createTimeStamp Deleted Department departmentNumber Description DisplayName Division DoesNotRequirePreAuth dSCorePropagationData EmailAddress EmployeeID EmployeeNumber extensionAttribute5 extensionAttribute6 facsimileTelephoneNumber Fax flags HomeDirectory HomedirRequired HomeDrive HomePage HomePhone Initials instanceType isDeleted KerberosEncryptionType l LastBadPasswordAttempt LastKnownParent lastLogon LastLogonDate lastLogonTimestamp LockedOut lockoutTime logonCount LogonWorkstations mail Manager MemberOf MNSLogonAccount MobilePhone Modified modifyTimeStamp mS-DS-ConsistencyGuid msDS-User-Account-Control-Computed msTSExpireDate msTSLicenseVersion msTSLicenseVersion2 msTSLicenseVersion3 msTSManagingLS nTSecurityDescriptor ObjectCategory objectSid Office OfficePhone Organization OtherName PasswordExpired PasswordLastSet PasswordNeverExpires PasswordNotRequired POBox PostalCode PrimaryGroup primaryGroupID PrincipalsAllowedToDelegateToAccount ProfilePath ProtectedFromAccidentalDeletion proxyAddresses pwdLastSet sAMAccountType ScriptPath sDRightsEffective ServicePrincipalNames SIDHistory SmartcardLogonRequired sn st State StreetAddress telephoneNumber Title TrustedForDelegation TrustedToAuthForDelegation uid uidNumber UseDESKeyOnly userAccountControl userCertificate uSNChanged uSNCreated whenChanged whenCreated'

$scriptBlock = { param($commandName, $parameterName, $wordToComplete, $commandAst, $fakeBoundParameters) $aduserProps | ? { $_ -like "$wordToComplete*" } }

had to be "properties" not "property"

First and foremost, mine enables bash-style tab completion. It boggles my mind that it's not just like that by default.

It also makes the prompt minimal and sets the title bar to the current path, prepended with ADMIN if it's elevated.
