In most projects, you ultimately have some data in rows and columns in text files. How do you get it there? I assume that you are using "grep" to extract it from a file. How do you manipulate it? That is what I will show now.
There are a couple VERY useful unix commands: paste and cut.
paste allows you to append files horizontally, line-by-line. Suppose you have file1:
1 2 3 4
and file2:
2 4 6 8 10 12 14
and you run
paste file1 file2
It will output:
1 2 2 4 3 6 4 8 5 10 12 14
