Removing repeating lines from a data frame (AWK)

Hey Guys!

I have written a code which combines lots of files into one big file(.csv).

However, each of the original files had headers on the first line, and now that I've combined the files the headers are interspersed throughout the new combined data frame. For example, throughout the data I will have a line;

//DATE TIME

FRAC_DAYS_SINCE_JAN1

FRAC_HRS_SINCE_JAN1 EPOCH_TIME

ALARM_STATUS

with each of these headers in a different column.

Is there a way of removing these lines when these headers arise?

Thanks!

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
