I have a couple of powershell scripts which I can use to do this. I use them when I take over a role if there is little source control and just as a precaution. They are useful for migrations too.

I forget where I got this one so I can't give credit to the initial author. I added a few modifications to it so...

# Date: 23/02/12

# Description: PS script to generate all SQL Server Agent jobs on the given instance.

# The script accepts an input file of server names.

# Version: 1.0

#

# Example Execution: .\Create_SQLAentJobSripts.ps1 .\ServerNameList.txt

#param([String]$ServerListPath)

#Load the input file into an Object array

$ServerNameList = "";

#get-content -path $ServerListPath

$login = Read-Host 'Enter your SQL login'

$password = Read-Host 'Enter your password' -AsSecureString;

$BSTR = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($password);

$PlainPassword = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR);

#Load the SQL Server SMO Assemly

[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.Smo') | Out-Null

#Create a new SqlConnection object

$objSQLConnection = New-Object System.Data.SqlClient.SqlConnection

#For each server in the array do the following..

foreach($ServerName in $ServerNameList)

{

Try

{

#$objSQLConnection.ConnectionString = "Server=$ServerName;Integrated Security=SSPI;"

$objSQLConnection.ConnectionString = "Server=$ServerName;User Id=$login;Password=$PlainPassword"

Write-Host "Trying to connect to SQL Server instance on $ServerName..." -NoNewline

$objSQLConnection.Open() | Out-Null

Write-Host "Success."

$objSQLConnection.Close()

}

Catch

{

Write-Host -BackgroundColor Red -ForegroundColor White "Fail"

$errText = $Error[0].ToString()

if ($errText.Contains("network-related"))

{Write-Host "Connection Error. Check server name, port, firewall."}

Write-Host $errText

continue

}

#IF the output folder does not exist then create it

$OutputFolder = "C:\Scripts\Jobs\$ServerName"

$DoesFolderExist = Test-Path $OutputFolder

$null = if (!$DoesFolderExist){MKDIR "$OutputFolder"}

#Create a new SMO instance for this $ServerName

$srv = New-Object "Microsoft.SqlServer.Management.Smo.Server" $objSQLConnection

#Script out each SQL Server Agent Job for the server

$srv.JobServer.Jobs | foreach {$job = $_.name -replace "\*", ""; $_.Script() | out-file "$OutputFolder\$job.sql"}

}

I'll need to try and find the other one. Its much easier to follow and uses SQLPSX.
