1. gzip.

$ ls
docker-compose.yml docker-compose-oracle.yml
$ gzip *.yml 
$ ls 
docker-compose.yml.gz docker-compose-oracle.yml.gz
$ gzip -d *.gz 
$ ls 
docker-compose.yml docker-compose-oracle.yml
$ gzip -k *.yml 
$ ls
docker-compose.yml.gz docker-compose-oracle.yml.gz docker-compose.yml docker-compose-oracle.yml

$ gzip --help 
BusyBox v1.31.1 () multi-call binary.

Usage: gzip [-cfkdt123456789] [FILE]...

Compress FILEs (or stdin)

        -1..9   Compression level
        -d      Decompress
        -t      Test file integrity
        -c      Write to stdout
        -f      Force
        -k      Keep input files

2. tar 

$ ls
docker-compose.yml docker-compose-oracle.yml
$ tar czf docker-compose.tar.gz *.yml 
$ ls 
docker-compose.yml docker-compose-oracle.yml docker-compose.tar.gz
$ gzip -d *.gz
$ ls

$ gzip -k docker-compose.tar
$ ls
docker-compose.tar docker-compose.tar.gz docker-compose.yml docker-compose-oracle.yml 
$ rm *.yml
$ ls
docker-compose.tar docker-compose.tar.gz

$ tar xzf docker-compose.tar.gz 
$ ls
docker-compose.tar docker-compose.tar.gz docker-compose.yml docker-compose-oracle.yml 

$ tar --help 
BusyBox v1.31.1 () multi-call binary.
