A: In GNU Screen press Ctrl + a + [ to enter Copy Mode, then scroll up/down using keys j or k. Below are some other navigation keys:

h -    Move the cursor left by one character
j -    Move the cursor down by one line
k -    Move the cursor up by one line
l -    Move the cursor right by one character
0 -    Move to the beginning of the current line
$ -    Move to the end of the current line.
G -    Moves to the specified line
       (defaults to the end of the buffer).
C-u -  Scrolls a half page up.
C-b -  Scrolls a full page up.
C-d -  Scrolls a half page down.
C-f -  Scrolls the full page down.

By the way, in order to define scrollback buffer size start screen with the following key (5000 lines in this example):

screen -h 5000

Quick info about GNU Screen utility: it is Unix tool that allows to run multiple applications in several “virtual” windows. It is very useful when you need, let’s say, to see hardware resources consumption caused by started application in different console etc. GNU screen is also good option to run applications remotely via ssh: just run application in screen and log off until it’s finished, then just “pick up” screen session and see how the application’s output.

Update: You can use activate copy mode of GNU Screen also by Ctrl + Esc that might be more useful than Ctrl + a + [ shortcut (thanks to Yu-Jie Lin for this tip).

The !$ command returns the last argument used with a command. But what happens if you have a command that used arguments and you want to reuse just one of them? The !:1 operator returns the argument used in a command. The example in Listing 3 shows how you can use this operator in combination with the !$ operator. In the first command, a file is renamed to a more meaningful name, but to preserve use of the original file name, a symbolic link is created. The file kxp12.c is renamed in a more readable manner, then the link command is used to create a symbolic link back to the original file name, in case it’s still used elsewhere. The !$ operator returns the file_system_access.c argument, and the !:1 operator returns the kxp12.c argument, which is the first argument of the previous command.

Listing 3
$ mv kxp12.c file_system_access.c
$ ln –s !$ !:1

Answer: You are welcome to use dmidecode which helps to get information about your system’s hardware as described in your system BIOS. That information typically includes system manufacturer, model name, serial number, BIOS version, asset tag as well as a lot of other details depending on the manufacturer.

Beware that DMI data have proven to be too unreliable to be blindly trusted. Dmidecode does not scan your hardware, it only reports what the BIOS told it to. Dmidecode was first written by Alan Cox and is now being further developed and maintained by Jean Delvare. It is released under the General Public License (GPL).

This tool can be easily downloaded from here (source code) or can be installed as binary package included into repositories of many distributions like Debian, Ubuntu, Gentoo. FreeBSD version is also available. Actualy it is reported that dmidecode works well on the following systems:

• Linux i386
• Linux x86_64
• Linux ia64
• FreeBSD i386
• FreeBSD x86_64
• NetBSD i386
• OpenBSD i386
• BeOS i386
• Cygwin i386
• Solaris x86 (CVS version)

In Ubuntu (my favourite distro) just execute the following: sudo aptitude install dmidecode (sample output is here).

1. Easy to configure and powerful MTA (Postfix)
2. Virtual domains and user accounts (this information is stored in MySQL database)
3. Antispam and antivirus checking for all accounts (spamassassin and clamav via amavis-new)
4. Secure access to mailboxes through POP3, IMAP and HTTP (squirellmail)
5. Secure SMTP server
6. Extremal Stability and Security

Actually OpenBSD 4.2 was chosen because of it’s “security by default”. Thankfully Daniele Mazzocchio from friendly site www.kernel-panic.it wrote an excellent article about how to build such mail server on this operating system:

Offering a reliable and secure email service is probably one of the top priorities of most system administrators; therefore, in the next chapters, we will build a full-featured mail server, based on open-source software and focusing on security. Read more…

The only thing that is not covered by it is mail content filtering with maildrop and vacation messages that users often ask to set while they are out. Working on it!

When you use a system often, you tend to fall into set usage patterns. Sometimes, you do not start the habit of doing things in the best possible way. Sometimes, you even pick up bad practices that lead to clutter and clumsiness. One of the best ways to correct such inadequacies is to conscientiously pick up good habits that counteract them. This article suggests 10 UNIX command-line habits worth picking up — good habits that help you break many common usage foibles and make you more productive at the command line in the process. Each habit is described in more detail following the list of good habits.

Those 10 good habits to adopt are:

1. Make directory trees in a single swipe.
2. Change the path; do not move the archive.
3. Combine your commands with control operators.
4. Quote variables with caution.
5. Use escape sequences to manage long input.
6. Group your commands together in a list.
7. Use xargs outside of find.
8. Know when grep should do the counting — and when it should step aside.
9. Match certain fields in output, not just lines.
10. Stop piping cats.

We announced big news today – our preliminary results for our fiscal second quarter, and as importantly, that we’re acquiring MySQL AB.
…
This puts products like MySQL in an interesting position. They’re a part of every web company’s infrastructure, to be sure. And though many of the more traditional companies use MySQL (from auto companies to financial institutions to banks and retailers), many have been waiting for a Fortune 500 vendor willing to step up, to provide mission critical global support.
