Project Description:
During the initial setup and implementation of the Web site, you have been reviewing some of the documentation, scripts and sample files that were installed on the Linux and Apache environments. In more than one place, you have noticed several familiar commands, but they have all been on one line. The ability of one command to send the output it generates to the input of a second command is a very important concept for the UNIX environment.

Describe the concepts of filters, pipes, and redirection and explain how and what the following commands are trying to accomplish (if some commands are not yet familiar, you can describe the overall process of each step):

1- ls /etc | grep conf | grep -v "\." | sort > ~/conf
2- cat /etc/passwd | awk -F":" '{print $1}' | sort >> ~/users 2>&1
The deliverable for the presentation should include:

3- A description of filters (including the 3 standard files every filter uses)
4- A description of pipes
5- A description of redirection
6- An explanation of the 2 commands above.


Adhere to MLA formatting and reference guidelines when writing your response. Additionally, your response should be free of grammatical errors, use complete sentences, and give specific details to support statements.
