There are several large collection of Linux Tips on the Internet. those are mixture of obsolete and useful tips so some work need to be done selecting valuable info from junk. Among them:
The Linux Tips HOWTO v3.6, June 1998 by Paul Anderson
Tips, Tricks, How-To from Fermilab.
Linux Tips Think of this as the LSADP (LinuxSA Documentation Project).
Linux Tips collection from Mike Chirico
For YUM tips one can look at Yum - Linux@Duke Project Wiki
Linux Gazette regularly publishes tips column. See for example More 2 Cent Tips! LG #106

As my journey continues with Linux and Unix shell, I made a few mistakes. I accidentally deleted /tmp folder. To restore it all you have to do is:mkdir /tmp chmod 1777 /tmp chown root:root /tmp ls -ld /tmp mkdir /tmp chmod 1777 /tmp chown root:root /tmp ls -ld /tmp

The variable CDPATH defines the search path for the directory containing directories. So it served much like "directories home". The dangers are in creating too complex CDPATH. Often a single directory works best. For example export CDPATH = /srv/www/public_html . Now, instead of typing cd /srv/www/public_html/CSS I can simply type: cd CSSUse CDPATH to access frequent directories in bash

I often find myself wanting to cd to the various directories beneath my home directory (i.e. ~/Library, ~/Music, etc.), but being lazy, I find it painful to have to type the ~/ if I'm not in my home directory already. Enter CDPATH , as desribed in man bash ):The search path for the cd command. This is a colon-separated list of directories in which the shell looks for destination directories specified by the cd command. A sample value is ".:~:/usr".Personally, I use the following command (either on the command line for use in just that session, or in .bash_profile for permanent use):This way, no matter where I am in the directory tree, I can just cd dirname , and it will take me to the directory that is a subdirectory of any of the ones in the list. For example:
CDPATH=".:~:~/Library"[ robg adds: No, this isn't some deeply buried treasure of OS X, but I'd never heard of the CDPATH variable, so I'm assuming it will be of interest to some other readers as well.]
$ cd $ cd Documents /Users/baumanj/Documents $ cd Pictures /Users/username/Pictures $ cd Preferences /Users/username/Library/Preferences etc...
cdable_vars is also niceCheck out the bash command shopt -s cdable_vars

From the man bash page:cdable_varsWith this set, if I give the following bash command:
If set, an argument to the cd builtin command that is not a directory is assumed to be the name of a variable whose value is the directory to change to.
I can then simply type
to change to my Desktop directory.
I put the shopt command and the various export commands in my .bashrc file.
Red Hat Knowledgebase
The dmidecode command can be used to display information from the systems' BIOS that includes the maximum memory that the BIOS will support. This information is displayed by dmidecode as type 16 (Physical Memory Array) which can be filtered with the command dmidecode -t 16.
For instance, the following output shows a system that can support a maximum of 16GB of RAM.
Handle 0x0032, DMI type 16, 15 bytes Physical Memory Array Location: System Board Or Motherboard Use: System Memory Error Correction Type: None Maximum Capacity: 16 GB Error Information Handle: Not Provided Number Of Devices: 4

RedHat Linux (should apply to 7.x and up)
This tutorial covers changing your hostname in RedHat Linux without having to do a reboot for the changes to take effect. I've tested this on RedHat 7.3, 9, Fedora Core 3, and CentOS 4.1. It should work for all the versions in between since they all closely follow the same RedHat configuration. What's the point of this tutorial? Never reboot if you don't have to and keep your uptime intact.
Make sure you are logged in as root and move to /etc/sysconfig and open the network file in vi.
Look for the HOSTNAME line and replace it with the new hostname you want to use. In this example I want to replace localhost with redhat9.HOSTNAME=redhat9
When you are done, save your changes and exit vi. Next we will edit the /etc/hosts file and set the new hostname.
In hosts, edit the line that has the old hostname and replace it with your new one.192.168.1.110 redhat9
Save your changes and exit vi. The changes to /etc/hosts and /etc/sysconfig/network are necessary to make your changes persistent (in the event of an unscheduled reboot).
Now we use the hostname program to change the hostname that is currently set.
And run it again without any parameters to see if the hostname changed.
Finally we will restart the network to apply the changes we made to /etc/hosts and /etc/sysconfig/network.
service network restart
To verify the hostname has been fully changed, logout of your system and you should see your new hostname being used at the login prompt and after you've logged back in.
Quick, painless, and you won't lose your server's uptime.
