Here’s a way to use getopt to handle arguments when creating command line applications. It works quite well with the standard help (–help or -h) by showing usage when bad arguments are passed.

This is useful if you need to look at the last arguments before deciding what to do, possibly for interoperability with some older code where the order of command line arguments is already set in stone.

You may find that grub is pretty useless when your menu.lst is missing or misconfigured. It’s not easy to figure out how to make grub tell you where the files are that you need. Here’s how to find what you need in order to boot, just using the grub bootloader.

I really like this tool, redirect the output to a file and it should dump the whole tree in seconds. All I was really interested in was the dn, cn, mail, and displayName, but I found I was able to see much more.

Find computers and their description from the AD, Use LDP to search for tombstoned objects in AD, Show all replicated attributes in the AD Schema, Show an AD schema attribute, Find a list of CNs in the directory and return their homeDirectory, Identify the DN of an Active Directory group, Query a user from AD using WMI, etc.

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!!?
