As a Linux sysadmin, I usually read the man pages but it looks like this time I needed extra help.
Your explanation was very helpful, now I understand how it works.
To set some background about myself, long ago I've done some basic shell scripting with bash and then I had to quit for a few years to do more orientated sysadmin tasks. It's kind of frustrating when you realise that you forgot a lot of things.
Now I want to catch up and expand my knowledge. I've also started learning about ksh, which is quite new to me.
Thanks a lot for your concern. I hope to be helpful as well.
