Do you ever find yourself running a command, pressing the up-arrow, then [Enter], then the up-arrow, then [Enter], then the up-arrow.... this is a great exercise that will get your fingers used to typing random odd key sequences without your eyes paying attention, but otherwise it's a complete waste of time. A command I have come to love helps me point my OCD tendencies to other pointless tasks while running commands over and over for me. Introducing 'watch', because Linux Just Does That.

For those cases where converting from Base64 encoded data to a hexadecimal output similar to what you get from other utilities this script may simplify your life. The script takes input and decodes it finally converting it to hex output for use in other applications.

In computing there are two terms which are often confused: encoding and enciphering. One of them, with 'cipher' in its name, usually best refers to something that is cryptographically enciphered which means it was mathematically mangled in a fashion that the result, regardless of the input, is fairly random, patternless nonsense to the un-key-assisted eye. The other term refers to simply changing data from one form to another at is basic level. One type of encoding is 'base64' encoding, which is used through many areas of computing and can be explained much more-simply than most cryptographic cipher functions (in my opinion). This article is to show how, on many levels, Linux Just Does That.

Since the release of eDirectory 8.8.0 support for multiple instances of eDirectory on a single box has been available. Using the ndsconfig and especially the newer ndsmanage tool configuring multiple instances of eDirectory is also very easy to do. One feature that has been missing since that time has been the ability to start/stop multiple instances as easily as one can start/stop the first root-based eDirectory instance of a root-installed eDirectory during startup/shutdown. The time has come to overcome that.

Sometimes I find myself wondering how big an installed RPM's files really are. Use a simple script to do all of the calculating of file sizes, plus see how to recreate the RPM from the system where the package is installed in the latest addition to Linux Just Does That.

You may well have learned the DD command to back up the MBR of a disk. Most servers and some desktops will have more than one hard drive. Also the hard drive device names may vary from hda to sda etc. Here is a simple universal script to provide a backup solution for your Master Boot Records.
