Hey there people on the internet. Here's my solution for Awk - 4 https://blog.shasec.rocks/post/hackerrank-bash-challs. So let's get started.
> An Introduction to 'awk'
There are a lot of quick tricks which may be accomplished with the 'awk' interpreter. Among other things, awk may be used for a lot of text-munging and data-processing tasks which require some quick scripting work.
Examples with awk
Only solutions using awk will be considered valid for this task
You are provided a file with four space-separated columns containing the scores of students in three subjects. The first column, contains a single character (A-Z) - the identifier of the student. The next three columns have three numbers (each between 0 and 100, both inclusive) which are the scores of the students in English, Mathematics and Science respectively.
> Input Format
There will be no more than 10 rows of data. Each line will be in the format:
[Identifier]<space>[Score in English]<space>[Score in Math]<space>[Score in Science]
> Output Format
Concatenate every 2 lines of input with a semi-colon.
> Sample Input
A 25 27 50 B 35 37 75 C 75 78 80 D 99 88 76
> Sample Output
A 25 27 50;B 35 37 75 C 75 78 80;D 99 88 76
Every pair of lines have been concatenated with a semi-colon.
