Here’s a short bash script to parallelize your jobs. There are utilities already written for just this type of thing, but forget xargs. Check out xjobs instead.

You have a bunch of related applications, each has their own Makefile that knows only about their own application, but you have dependencies where one app needs to be built before another. Here’s a skeleton bash script for building any one thing or everything.

#!/bin/bash

function build {
echo "*** …

This is so handy, I can’t believe i’ve never used or even heard of this until today! You can easily run your bash shell scripts in debug mode to watch what they’re doing behind the scenes in real time. You get to see the levels of nesting when you’re inside loops and variables get replaced with their actual contents at the time of execution.
This might come in handy if you have multiple levels of nesting in ‘for’ and ‘while’ loops or a few if/then/else statements and you want to see just what is getting passed in the comparisons.

Instead of typing the export string out each time and the emerge line too, I just recalled them from the history knowing that the last set of commands that started with those characters were the commands I wanted. If you didn’t know about these handy shortcuts, now you know, and knowing is have the battle. So when is that movie coming out anyway!!?

shc is the only tool i’ve found that will compile scripts so idle hands won’t tamper with your bash shell scripts. Yes, I know I could just use permissions to keep people from reading them and it’s easy to reverse engineer the binary code, but I look at it like …

[user@localhost ~]$  cat ~/.ssh/id_rsa.pub ~/.ssh/id_dsa.pub | ssh user@remotehost ’sh -c “cat - >> ~/.ssh/authorized_keys”‘
You’ll be prompted for the password just this one last time.  This is perfect for running a script that runs several remote commands through ssh.  Here’s a script that checks for your keys and adds them if …

Yes, I know this is ancient stuff, but I have no choice but to mess with it right now.  Old ultrasparc garbage, weeee!  So here goes the installation of some ‘modern day’ packages so I can work with this old box.  (It hasn’t been touched since 2002, ouch)
First you’ll need …
