Konverterar powerpoint filer till pdf från prompt eller via skript (spara som .ps1 fil och kör där pptx filerna ligger) [källa] [Hej]
!OBS! Ta bort nedersta raden, den gör bara namnbyte på filerna enligt mitt eget tycke!

Bash
Testa om en viss port är öppen på en lista hostar
#This is a bash script to check ssh services on hosts
#You need a host file with each IP-address on a separate row
#The source file for the text is used as an argument, ie ./ssh-check.sh ip.txt
#Edit the nc row to alter the port you are testing for, in this case its ssh=22
#Results are output to screen and a text file in the same directory
#!/bin/bash
echo "=================================="

then

Genererar QR koder från en lista
# This is a bash script to generate qrcodes by reading a text string

PowerCLI för VMware (körs i Powershell! - spara som powershell skript...)
För att skapa en mängd VLANS utan att sitta manuellt i Vcentret (obs PowerCLI är farligt!)
// 1. behövs för att köra vm-ware modulen i windows då den är "tredjepart"
Set-ExecutionPolicy remotesigned
// 2. -Scope begränsar installation till inloggad användare
install-module -Name VMware.PowerCLI -Scope CurrentUser
// 3. Kommer att fråga om dina credentials, använd samma som gui inloggningen
Connect-VIServer -server vcenter-b.cnap.hv.se
// 4. länk till object som är h6 hosten (till exempel)
$myVMHost = Get-VMHost -name esxi-h6.cnap.hv.se
!! VA RIKTIGT RIKTIGT SÄKER PÅ ATT DET ÄR HÄR DU VILL PILLA !!
// 5. länk till vswitch som skall pillas på
$vswitch = Get-VirtualSwitch -vmhost $myVMHost -name vSwitch1
// 6. Skapar VLAN med namn "VLAN20XX" och vlan id 20XX
for ($i=2004; $i -le 2038; $i++) {New-VirtualPortGroup -VirtualSwitch $vswitch -name "VLAN$i" -VLanId $i}
// 7. tar bort portgroups "VLAN2037-VLAN2038" på vswitchen som definieras i steg >>5<<
// OBS! -confirm:$false stänger av en "are you sure, dummy" fråga. Är du inte säker, ta bort detta ur raden! OBS!
for ($i=2037; $i -le 2038; $i++) {Get-VirtualPortGroup -VirtualSwitch $vswitch -name "VLAN$i" | Remove-VirtualPortGroup -confirm:$false}
// Bryt kopplingen till vcentret
