Unix HW 5

[Spring 2018]

IFT 250: Shell & Script Programming with Unix

Lab Activity 5: Formatting with grep, sed, and awk

For the following labs include the following header in your scripts:

#!/bin/bash

# File name: <filename of your script>

# Author: <Include your full name here>

# Term: <Spring 2018>

# Date: <Include the date you created the script>

Be sure to also include detailed comments in each script!

Part I: Historical artifacts

The oldest commands in UNIX/Linux are found in the /bin directory. They are simply two letters and the preform a single very specific task, but they preform it very well.

Write a shell script called lab5.1 to search the /bin directory and find all commands that are made up of two lower case letters. Your script should save the list of commands, as well as the number of commands found, in a file called lab5.1.out.

Part II: Live Free or Process Data

Consider the files L2E1.iva, L2E2.iva, and L2E3.iva from your lab2E. This is raw performance data collected on a solar photovoltaic module installed at the ASU Polytechnic campus. This data must be processed to determine the performance output of the system or panel. The 3 files correspond to 3 repeated measurements.

Write a shell script called lab5.2 which uses the tools you have learned in this unit, including at least one use of regular expressions , grep , sed , paste , and awk , to extract, edit and format the necessary data from the three files to resemble the processed data below:
