If you’ve worked in Windows long enough, you have come across the .chm file format. This format is nothing more than a compressed html directory with an included index for easy viewing. Problem is, you can’t view these files in Linux without the help of another tool. And sometimes you want to be able view these files in another format.

Suppose you have a directory full of files with filenames such as oldfile, my-new-file, some_document. Suppose you would like to rename these files to File1, File2, file3.

MPlayer is a pretty powerful tool for processing video files. It has a built-in command line option that will export specified movie frames to a GIF. Such a feature seems like it would make the guide I'm presenting here obsolete, but the problem with the feature is that the resultant GIF looks terrible: too few colors.

Locating files that you know exist, but you can’t remember where they are can be frustrating. There are a handful of GUI-based search tools for Linux and Unix, but if you prefer to work in the command line, or don’t have one of these special apps installed, you can often fall back on command line tool locate.
