I’m trying to write a BASH script that will append :00:00 to the end

I’m trying to write a BASH script that will append :00:00 to the end of all values in the 2nd field of a CSV file.

I’ve tried reading through ‘awk’ man pages but I’m not understanding how I can complete this. Any help is appreciated!

    Below is a command to filter the conversion:

    awk 'BEGIN { FS=","; OFS="," } (NF>=2) { $2=$2 ":00:00"; } (1)'

    If you have a file source.txt which store source data and a file result.txt to be stored the output, following command will do:

    awk 'BEGIN { FS=","; OFS="," } (NF>=2) { $2=$2 ":00:00"; } (1)' source.txt >result.txt

    If you have multiple input files, you can add them in arguments.
    See manpage of awk for more details.
