Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Im taking a network security class and we are trying to find exploits but Im having trouble cd into a folder with a name of ".." (two periods) It is an actual folder and an ls -al in the directory shows a . .. and another .. highlighted in green. Im stuck figuring out how to prevent it from taking .. as a parent command.
The cd command doesn't interpret ".." as a command; the ".." directory is a real directory link that leads to the parent directory.
If a second directory shows up as ".." in the directory listing, the name must be different somehow; a leading or trailing space, a non-printable character somewhere in the name, or one or both dots could be another character entirely, but one that looks similar to the punctuation mark.
You could try processing the directory with a "for" or "while" loop, or try using the autocomplete feature of the shell. If all else fails, run fsck on the file system to rule out a file system error.
