I was working on a script that parsed log files. The file names were log.mmddyy (log.080811). This was a little bit of a learning experience for me (new to shell scripting). I was working on a Solaris 10 box, but I thought I’d do all my dev/testing on Ubuntu. Big mistake. Linux was running bash/gnu tools. Solaris was not. After I figured out how to do it on Ubuntu, I had to figure out how to do it on Solaris (thanks Scott!), then I did it in Powershell (had done something similar already for another script) and since I’m teaching myself Python, I wanted to do it in Python.
Are they the “right” way to do them? They work! Probably not a “right” way to do them, as there is always more than one way to do something
Shell
#!/bin/bash
os=`uname`
if [ $os == 'Linux' ];
then
yesterday="$(date -d 'yesterday' +%m%d%y)"
echo $yesterday
elif [ $os == 'SunOS' ];
then
yesterday=`TZ=GMT+24 date +%m%d%y`
echo $yesterday
fiGnu Date
#!/usr/bin/bash
## Get Yesterday
yesterday="$(date -d 'yesterday' +%m%d%y)"
Powershell
$yesterday = (get-date -format mmddyy).adddays(-1)
$yesterday.tostring('MMddyy')Python
import datetime
today = datetime.datetime.today()
one_day = datetime.timedelta(days=1)
yesterday = today - one_day
yesterday.strftime('%m%d%y')

Quick, Dirty, Simple. Set the default printer with Powershell. Needed this as a part of a logon script to set default printer for certain users on a terminal server.
## Get the Printer with WMI
$printer = Get-WmiObject -Query "Select * from Win32_Printer Where Name = 'PDFCreator'"
## Set printer as default printer
$printer.SetDefaultPrinter()
