In SNPTEST output, the header get “#” and “alternate_ids” which I don’t want to process.
with awk, it is quite simple to skip these lines with regrex:
cat snptest.out | awk ‘!/#|alternate_ids {print $0}’
OFS=$”\t” can use tab as output seperator
NR line number, if you know how many lines you don’t want in the header, do
cat snptest.out | awk ‘{if(NR>n){print $0}}’
