To compress many files do as shown below:
Bash is the command-line interface for Gnu/Linux OS, it is the clone of Unix OS command-line interface a.k.a CLI. It is commonly used by Sysadmins, programmers and it is handy for every Gnu/Linux user.
I first used a Gnu/Linux OS back in 2008 just for fun, however, I was obliged to get back to it as I was not satisfied with WSL of MS Windows 10 to learn and use WP-CLI.
My main OS now is Ubuntu, I use it for my translation work and programming as well. Meantime, on a few occasions, I have to use MS Win 10 if some programs for my language services work best on Windows and it could be counterproductive to use an emulator such as Wine.
If appropriately learned it helps speed up many tasks either with commands or using bash scripts.
