Transforming a Data Set into a Formatted Output in Unix
If you're working with data sets in Unix and need to manipulate and reform it into a more usable format, you might find yourself needing to transform a simple structured text file. In this guide, we'll explore how to create a Bash script that takes an input file containing data and outputs it in a specified format.
Let’s say your input data looks something like this:

The Challenge
Step-by-Step Solution
Step 1: Create Your Input File
Step 2: Write the Bash Script

Step 3: Explanation of the Code
Let's break down the code for clarity:
# !/bin/bash: This line denotes that the script should be run in the Bash shell.
f=$(awk -F" " '{print $1}' <<< $i): This extracts the first field from the input line (the ID).
line=$(cut -d" " -f2 <<< $i): This gets the second field, which is the comma-separated values.
for m in $(echo $line | sed "s/,/ /g"); do: This converts the comma-separated values into space-separated values for easier iteration.
echo $f " " $m: This prints the ID followed by each corresponding value.
Finally, the loop continues reading until all lines are processed.
Step 4: Running the Script
To execute your script, simply run the following command in your terminal:

Conclusion
With just a few lines of Bash scripting, you can efficiently transform your data sets into a much more readable format. This process not only saves time but also enhances your ability to work with large datasets in Unix.
As you explore more Unix commands, you will find even more ways to manipulate data to fit your requirements. Happy scripting!
