The linux/unix philosophy has been to make sure programs do a job, and do it very well. No need to make wget or git clone. Just use them and learn and understand how those commands work, learn more about the commands then if you get to a place where you realise theres something you want to do but no command for it then you can play and experiment with using alias's, piping commands, rdirection and writing some scripts. Try learn which commands exist and what they do then you will get a feel for how the commands work.I want ot create cmd like wget , git clone
Just for learning
