Three implicit if clauses, followed by {action} where each action ends with a jump to the next...

There we go. It makes it much easier to help when relevant examples are given ;)
So I made an example of your given input and arranged some matched in file1 and file2.

Try:

I guess the below command stops printing after it encounters a "-" in 2nd column.
awk '$2 ~ !/-/{print $0}' filename

Try:awk 'NR==1{for (i=1;i<=NF;i++) if ($i~"^Peak.Area") {printf $i" ";a[i+1]=1};printf "\n"}

awk -F ' ' '{printf "%s\t%s\t%s\t%s\t%s\t%s",$15,$2,$0,$16,$4,$5;}' <test.txt> test.bim
