Video Cygwin Notes

A few notes for myself on Shell

• The shell is a program running within the terminal.
• There are many available to run in the terminal.
• Each shell has a certain style of how it presents itself in the terminal and different patterns of working with input/output. 

Bash Shell

• One of the many shells available.
• Usually a default shell.

Layout of Unix

• / = root directory
• /bin = Programs found here
• /etc = Configuration and data files.
• /dev = Lists attached devices such as files.
• /home = Users home folders stored here.
• /lib = Library files program depend on.
• /tmp = temporary file cache.
• /usr = programs accessed by users. 
• /var = variable file size cache for temp files.

Navigating Directories

• cd = change directory
• cd /  to go to the root directory.
• cd.. to go to the parent directory
• pwd = Print working directory (of what you're looking at at the time)
• ls = lists files and folders (warning that it might list alot)
