https://stackoverflow.com/questions/19602181/how-to-extract-one-column-of-a-csv-fileThe tool that would be best suited for retrieving specific fields from a CSV file is "awk."
Awk is a powerful command-line tool for manipulating text files that is included in most Linux distributions. It is designed to search and process text files, with a focus on pattern matching and data extraction. It is commonly used to extract specific fields from a file, as well as for data processing, formatting, and reporting.
In the case of a CSV file, awk can be used to extract specific fields using the delimiter (usually a comma). For example, if we have a CSV file with the following data:
Name, Age, Gender John, 30, Male Jane, 25, Female Bob, 45, Male
We could use the following awk command to extract only the Name and Gender fields:
swiftawk -F, '{print $1, $3}' file.csv This command tells awk to use the comma (",") as the field separator (-F), and to print out the first and third fields ($1 and $3) from the file "file.csv". The output would look like this:
Name Gender John Male Jane Female Bob Male
In contrast, the other options listed are not as well suited for this task:
