What Is GREP and How Do You Use It?

Grep is a small Unix program for finding matching patterns. Begun as a Unix program, it can be found on Linux as well as Mac and BSD. It can read just about any text, meaning it can read input from another commands, or it can open and look through files directly. Grep is insanely useful, especially for looking through directories from the command line.

Understanding Linux Permissions

Linux is a multiuser operating system. In a multiuser environment, it is necessary to ensure that a user cannot access or modify files or directories that they arent supposed to. File permissions provide a protection mechanism for controlling access to files and directories.

Linux’s file security model is based on that of Unix. Each file or directory can be accessed or modified by the user who created it, or a group of users who have been given permission to do so. Permissions can also be defined for other users that do not belong to either of these two categories.

In this guide, we will go over how file permissions work in Linux for beginners. We’ll cover how you can view the permissions associated with files and directories and also how you can change them.

Keep local Instant Messages on your local network with BeeBEEP (Secure Lan Messenger)

When you want to send an instant message to someone else that’s on the same local network as you are, whether that be another family member or a co-worker in your office, why use an offsite chat server that leaves your messages open to interception by the company running the chat server or some other third party? This software will allow you to keep your local IM’s in your local network, and for added safety it also encrypts them! Plus, it supports multiple operating systems, unlike the proprietary chat client that might have come with your computer. It’s NOT for chatting with people elsewhere on the internet; if you need to set up secure connections with offsite chat clients then you may need to set up a private Prosody IM server. But for secure IM chats with people on your local network, this looks like just the thing!

What is BeeBEEP?

BeeBEEP is an open source, peer to peer, lan messenger developed by Marco Mastroddi. You can talk and share files with all the people inside your local area network such of an office, home or internet cafe. You don’t need a server, just download, unzip and start it. Simple, fast and secure.
