awk regrex pattern

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}}’
