Converting "Mixed Case" filenames to "Lower Case"

Just a head's up on a pretty cool site that I came across today: Command-Line-Fu

Removing Deleted Files from your Trash

Have you ever deleted files to your "Recycle Bin" or if you prefer "Trash" only to find you cannot use "Empty Deleted Items" observing that permissions prevent you from deleting all the files or folders your bin contains.

Tar file archiver and compression utility

In computing, tar (derived from tape archive) is both a file format (in the form of a type of archive bitstream) and the name of the program used to handle such files. Initially developed as a raw format, used for tape backup and other sequential access devices for backup purposes, it is now commonly used to collate collections of files into one larger file, for distribution or archiving, while preserving file system information such as user and group permissions, dates, and directory structures.

The problem

Whilst trying out new Conky config files on Crunchbang Linux (wiki to follow about this) I had a few problems that turned out to be fonts that were needed that I did not have installed. A quick web search later and the fonts were downloaded, but how do I install them so the system knows about them??

Background

Espeak A Very Easy and Powerful Festival Alternative

Festival for many years has been the mother of all vocabulary text to speech systems available however it is complex to install especially if you need other voices. Espeak takes the pain out of installation that can challenge the most accomplished or seasoned Linux user. Ubuntu comes with Espeak pre-installed and even if this is not installed it only takes seconds to do so, unlike festival which takes many minutes.

Video Tools in Linux

Backup and Restore

A hard disk can be composed of many things but essentially the only data it holds is a series of 0 (zero's) and 1 (ones) most of what is contained within a hard disk therefore is empty space ie a 0 (zero's) that being the case it should be possible to design an algorithm that takes advantage of this and save only the data needed, well we have news for you such an application is already available.
