How To Merge Two Fastq.Gz Files?

With gzip files, you can simply concatenate the files using `cat`:

cat sample1_R1.gz sample2_R1.gz file3.gz > sample_merge_R1.gz

cat sample1_R2.gz sample2_R2.gz file3.gz > sample_merge_R2.gz

You can also do this:

zcat sample1_R1.gz sample2_R1.gz file3.gz |gzip - > sample_merge_R1.gz
zcat sample1_R2.gz sample2_R2.gz file3.gz |gzip - > sample_merge_R2.gz
