wget tutorial: Command line downloads

Up
vote
Down

Automate your http downloads with wget...
Despite the fusion of some browsers with file managers many still do not support the multi-selection and rubber banding operations that make it easy to transfer several files all in one go. You also have to stay logged in until the entire file has arrived. Finally, you have to be present at the office to click the link initiating the download, thus angering coworkers with whom office bandwidth is being shared.

Downloading of large files is a task more suitable for a different suite of tools. This article will discuss how to combine various GNU/Linux utilities, namely lynx, wget, at, crontab, etc. to solve a variety of file transfer situations.

Easing SLES 10 command line administration

Down

The author of "The Definitive Guide to SUSE Linux Enterprise Server" talks about SGID and SUID uses, how to make device sharing easier and more.
Advanced permissions can be very useful, but very dangerous as well. Let's talk about SUID, first. This permission is meant to be used on executable program files only when strictly necessary. In my opinion, it is better not to use them at all. They can provide an excellent backdoor for a hacker if used not in the right way.

Eric S. Raymond isn't just an open source evangelist -- he's a coder too.
We're going to look at a few programs he maintains -- if we can borrow a phrase from another famous coder -- just for fun.

The download page for each of these games is linked to from the game title in the section heading. A man page is included with each source code tarball. You should probably consider reading the man page a prerequisite for game play.

Command line web browser: Lynx

I use Lynx every day. No, really...
This time I've gone too far. Espousing the use of a text-based web browser is like encouraging honesty at Microsoft. The very notion of a text interface for the Web runs against the grain. Nonetheless, that's what we're doing this week here on the CLI frontier. Come read about a lean, mean, text-based browsing machine that's faster than a lynx. Actually, it is a Lynx.

CLI vs. GUI: The case for the command line shell

Up
vote
Down

There are good reasons why a GUI can never replace bash and friends.
I do not think that typed-in commands must necessarily be consigned to the dustbin of computer history. Of course, I am not suggesting that we all drop X and Windows and pretend like we are living in the early eighties. The command line interface still has much to offer us, and many of its benefits simply cannot physically be emulated or even replaced by graphical ones.

In this article, I will be analyzing the specific properties that make the command line unique and irreplaceable. I will likewise analyze the graphical UI's features--though only giving it a cursory look, since I assume my audience does not need to be persuaded to make the most of its video hardware.

But, constantly logging in to and out of MySQL just to execute a simple query is aggravating. However, if you're otherwise logged in to the server, you can create a shell alias that will log in to the MySQL server, select the appropriate database, and execute a specific command:

Unlike virt-manager, virt-install is a command line tool that allows you to create KVM guests on a headless server. You may ask yourself: "But I can use vmbuilder to do this, why do I need virt-install?" The difference between virt-install and vmbuilder is that vmbuilder is for creating Ubuntu-based guests, whereas virt-install lets you install all kinds of operating systems (e.g. Linux, Windows, Solaris, FreeBSD, OpenBSD) and distributions in a guest, just like virt-manager. This article shows how you can use it on an Ubuntu 11.04 KVM server. read more...

Backups aren't important -- until you need them.
Quick. When is the last time you backed up your system? Unless you are a system administrator by trade, I bet 95% of you haven't done so recently. If you suffer a hard drive crash, you stand to lose all your recent email, work, notes, photos, bookmarks, and whatever. One reason for that might be the paucity of a easy to use backup tools. Let's bury that reason once and for all.

Nail: Linux command line mail

Up
vote
Down

I still type 'mailx' out of habit, but it's just a link to nail on my system.
Nail is a lightweight console-based mail client, made to be a modern replacement for the ancient mailx command. It's fully compatible with mailx, but has a lot more features, which makes it appropriate for everyday use. Nail supports POP3, IMAP, and SMTP out of the box, so there's no need for further programs like Fetchmail or Postfix. It also has a built-in Bayesian spam filter, so you don't need external tools like SpamAssassin.
