Editing FreeBSD

[[BSD]] stands for '''B'''erkeley '''S'''oftware '''D'''istribution and is an [[operating system]]. Most of its common variations are considered to be Free/Libre and Open Source Software ([[FLOSS]]). This resource is similar to its counterpart [[Linux]] and one should explore things like [[Basic commands in Linux]] and [[Directories in Linux]]. Most work for the BSDs also. [[FreeBSD]] is what we'll be looking at primarily but we will also cover [[NetBSD]], [[OpenBSD]] and others.

== Getting FreeBSD ==
[http://www.freebsd.org/where.html Getting FreeBSD] is easy. This course is based on the [http://www.freebsd.org/releases/7.2R/announce.html FreeBSD 7.2-RELEASE] which came from [ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/7.2/ here]. If you are new to installing [[operating systems]], you might consider getting only the <kbd>7.2-RELEASE-i386-livefs.iso</kbd> to look at a [[Live CD]] version. [[PC-BSD]] and [[FreeSBIE]] are also available. You can also learn FreeBSD if you have an Amazon [[AWS]] account, as there is free version available on [[AWS Marketplace]], and probably some other cloud hosting providers offers too FreeBSD installations.

<small>''see also [[Creating a bootable disk]]''</small>

== Learning BSD ==
We chose FreeBSD for the i386 family. Look again at the [http://www.freebsd.org/where.html Getting FreeBSD] page to see if it matches your test machine. If you don't have a test machine, there are many BSD servers online where you can get a [[shell account]].

==Basic Commands ==
* CPU Information: <code>[[sysctl]] hw.model hw.machine hw.ncpu</code>
<pre>
user@example.com# sysctl hw.model hw.machine hw.ncpu
hw.model: Intel(R) Xeon(R) CPU E3-1230 V2 @ 3.30GHz
hw.machine: amd64
hw.ncpu: 8
</pre>

* Memory installed: <code>sysctl hw.physmem</code>

Package Management [[Packages]]: 
* List installed packages: <code>[[pkg]] info</code><ref>https://www.freebsd.org/cgi/man.cgi?query=pkg&sektion=&n=1</ref>
* Install a package <code>pkg install package_name</code>
* Delete a package <code>pkg delete package_name</code>

== Installing FreeBSD ==
Our CD set:
*<kbd>7.x-RELEASE-i386-bootonly.iso</kbd>
*<kbd>7.x-RELEASE-i386-disc1.iso</kbd>
*<kbd>7.x-RELEASE-i386-disc2.iso</kbd>
*<kbd>7.x-RELEASE-i386-disc3.iso</kbd>
*<kbd>7.x-RELEASE-i386-docs.iso</kbd>

Our Hardware:
Our test machine will be a Dell PowerEdge 2400 server with one i386 class Pentium IV (even though there is a socket for a second).

== Updating FreeBSD ==
FreeBSD updates can be done using <code>freebsd-update</code> command.

==Managing Service ==
Services are managed using <code>service</code> command and the <code>start</code>, <code>stop</code>, and <code>restart</code> options.<ref>https://www.freebsd.org/doc/handbook/configtuning-rcd.html</ref>

== Personalize command prompt ==
You can personalize your [[command prompt]] by editing <code>~/.cshrr</code> file.
Change set prompt line to your desire value, for example:
<code>set prompt="%{\033[46m%}[$HOSTTYPE]`uname -r`%B[%.2]%b"</code>
