循环并打印和求和列 linux

Question

I want to go through 22 data sets labeled the same by chr1- chr22. This is what one file looks like. als.sumstats.meta.chr10.txt.gz. I want to unzip these files and extract all data from columns $2,$1,$3,$9 and in a new column sum $14 and $15. I want to then zip these files up when I am done. I want to return an appended table with all data from each of the above columns for downstream analysis. This is what I have and am having trouble with the zipping/unzipping part.

#!/bin/bash

FILES=/ALSsummaryGWAS/Summary_Statistics_GWAS_2016/als.sumstats.meta.chr{1..22}.txt.gz
for f in $FILES;
do
  echo "$FILES"
  echo "extracting columns 2,1,3,9"
  awk '{print $2,$1,$3,$9, $14+$15}' > ALSGWAS.txt
done

Answer 1

for f in $FILES; do
  gzip -d < $f | awk '{print $2,$1,$3,$9, $14+$15}' | tee -a all.txt | gzip > $f.sub
done
