Quick Tip

Leveraging `paste` for Powerful Text Column Manipulation

Challenge: You have multiple files, each containing a single column of data, and you need to combine them into a single file, aligning the data into new columns.

The Solution: Use the `paste` command with a delimiter.

paste -d',' file1.txt file2.txt file3.txt > combined_file.csv

Why it works: The `paste` command merges lines of files. The `-d’,’` option specifies that a comma should be used as the delimiter between the columns from each input file. The output is redirected to `combined_file.csv`.

Pro-Tip: If you want to combine multiple files into a single line (column-wise) without any delimiter, simply omit the -d option: paste file1.txt file2.txt > single_line_file.txt
