分割文件后生成标题和尾部

Question

This is coding that I already do splitting:

awk -v DATE="$(date +"%d%m%Y")" -F\, '
    BEGIN{OFS=","}
    NR==1 {h=$0; next} 
    { 
        gsub(/"/, "", $1); 
        file="Assgmt_"$1"_"DATE".csv"; 
        print (a[file]++?"":h ORS) $0 > file
    }
' Test_01012020.CSV

but then, how can I add some header and trailer into above command?

    NR==1 {h=$0; next} 
    { 
        gsub(/"/, "", $1); 
        file="Assgmt_"$1"_"DATE".csv";
        print (a[file]++?"":DATE ORS h ORS) $0 > file
    }
    END{for(file in a) print "EOF" > file}
' Test_01012020.CSV
