GNU find is a powerful command-line utility that lets you search for files and folders in a hierarchical tree directory structure. It is the backend for all those utilities out there like the graphical searching in KDE or GNOME. However, find can be a little hard to handle at first by beginners. In this tutorial I will try to explain some of the capabilities of find, show some useful one-liners and provide more explanations regarding this command.

This article is about two popular IM (Instant Messaging) clients that can be used in a terminal instead of a graphical environment. Both have advanced features and are based on the ncurses library.

Finch
Based on libpurple, Finch is developed by the Pidgin project, and it pretty much supports the same features of it, except for the graphical part, of course. There are many chat protocols which it supports, including AIM, IRC, MySpaceIM, WLM, SILC, Yahoo! or ICQ.

telnet
telnet is a well-known command-line tool which uses sockets to open a TCP connection to the specified hostname and port. telnet can be primarily used for non-secure connections to connect to a HTTP server and get a file or to an IRC server for example.

cmus
cmus is a music player that I admire the most when it comes to command-line because it’s really powerful and has a lot of nice features. It is built with ncurses and therefore providing a text-user interface. cmus is indeed feature-rich, with several view modes and Last.fm song submission support via scripts. It supports Vi-like commands and auto-completion with Tab too. Recently I wrote a full guide on how to use cmus, you can read it here.
