Current profile - just a few useful aliases and functions for what I often do in PowerShell

Microsoft.PowerShell_profile.ps1

Function Touch-File
{
    $file = $args[0]
    if($file -eq $null) {
        throw "No filename supplied"
    }
if(Test-Path $file)
    {
        (Get-ChildItem $file).LastWriteTime = Get-Date
    }
    else
    {
        echo $null > $file
    }
}
Set-Alias touch Touch-File

Function Import-SPOModule
{
    Import-Module Microsoft.Online.SharePoint.PowerShell -DisableNameChecking
}

Function Connect-Exchange {
    $O365Cred = Get-Credential
    $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $O365Cred -Authentication Basic -AllowRedirection
    Import-PSSession $Session
}

Function Sign-Script {
    $file = $args[0]
    if($file -eq $null) {
        throw "No filename supplied"
    }
    else {
        $cert = Get-ChildItem cert:\CurrentUser\My -codesign
        Set-AuthenticodeSignature -FilePath $file -Certificate $cert[0]
    }
}

Removed alias for Sublime since Sublime Text 4's subl.exe can be added directly to PATH
