I'd like to combine those awk statements:
awk -F'\t' 'NF>1 && $NF!=""' #prints every row with more than two fields awk '$1 ~ /^[0-9]/' #prints every row starting with a number awk -F'\t' 'NF==1' #prints every row with one only field awk '$1 ~ /^[A-Z]/' #prints every row starting with a capital letter
in order to get a statement printing every row that begins with a capital letter AND contains one only field, and every row with more than two fields, each of them starting with an integer.
NAME_1 1 11 11 key 11 KEY KEY
NAME_1 11 11
