How to decompress several fastq.gz files into one single file?

[Madza Farias Virgens]

How to decompress several fastq.gz files and concatenate them into one single .fastq file? There are two kinds of file in the same folder, some ending in ...R2_001.fastq.gz , and others ending in R1_001.fastq.gz. The work is to decompress and concatenate files ending in ...R2_001.fastq.gz into one R2_001.fastq file, and do the same for ...R2_001.fastq.gz files. Really appreciate any help. Thanks -madza

gunzip decompresses gz files, cat concatenates them, and * is a wildcard. This is all in the Unix command line once you've moved to the directory with the files.
gunzip *R2_001.fastq.gz
cat *R2_001.fastq > combined_R2_001.fastq

zcat *R2* > concatenated_R2.fastq.gz
zcat *R1* > concatenated_R1.fastq.gz
