Historical Artifacts

Part I: Historical artifacts

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

Write a shell script called lab5.1to search the /bindirectory 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.ivafrom 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 calledlab5.2which uses the tools you have learned in this unit, including at least one use of regularexpressions, grep, sed, paste, and awk, to extract, edit and format the necessary data from the three files to resemble the processed data below:
