Quick tip: Enhanced bash completion in Fedora and CentOS

Expand swap space (virtual memory) on a Linux machine
Linux needs swap space or virtual memory to expand the real memory (RAM), and believe me it won't work as expected all the time if there is no sufficient swap space. Swap space usually is setup as a separate partition which is set during installation or later by the system administrator. But sometimes you need to create extra space for virtual memory for any purpose (Oracle installation for example). But if you don't want to mess up with your hard disk, here is a simple way to create a file which serves as a swap partition.
Unix/Linux shell in windows
Do you want the powerful Unix/Linux shell right on your windows desktop? It is very easy to get it working, just install Cygwin. Cygwin is a Linux-like environment for Windows. It enables you to have most powerful Linux commands and shell programs like bash shell, vim editor, grep, OpenSSH server & client and much more.
After installing Cygwin it will put an icon on your desktop to run the shell. A small tip to access your hard drive partitions is found under the directory /cygdrive/ with every partition found with its name (c, d, ...) .
Cygwin installation
If you wanted to add/remove programs you can use the setup file anytime.
