Such a long time, 1 week to learn a new language, having known a little about concurrency.
Not so bad.
AcknowledgeGo is a new language. Although it borrows ideas from existing languages, it has unusual properties that make effective Go programs different in character from programs written in its relatives.The notes below was written from the view of a CPP programmer.

What is shell?
The shell is a program that takes keyboard commands and passes them to the operating system to carry out.
Almost all Linux distributions supply a shell program from the GNU Project called bash.
Bash is an enhanced replacement for sh, the original Unix shell program written by Steve Bourne.
What is terminal emulator?
We use a terminal emulator to interact with the shell when using a GUI.
KDE uses konsole and GNOME uses gnome-terminal, though it’s likely called simply “terminal” on our menu.
Shell prompt[me@linuxbox ~]$
Some Simple Commands
date - Display the current time and date.
cal - Display a calendar of the current month.
df - Display the current amount of free space on your disk drives.
free - Display the amount of free memory.
exit - End the terminal session.
