Linux command structure:
    cmd [options] [input]

Linux directory:
    A folder and directory are the same thing
    Think of a folder as a branch point in a tree, and files are the leaves
    The top folder is called the "root" and is reference by '/'
    The current directory is referenced by '.'
    The parent folder of the current directory is referenced by '..'
    '~' is used to reference YOUR home folder
    '~username' is used to reference username's home folder
    A path is a list of folders that form a path on the directory tree
    A path that starts with '/' is called absolute since it gives the
        full from root to where you want to go
    A relative path does not start with '/' and instead appends the
        current directory to start (i.e. it adds ./ to begining of given
        path.

mkdir subfolder
mv tiltseries.jpg subfold
ls
file subfold
mv subfold subfold.pdf
file subfold.pdf
mv subfold.pdf subfolder/
ls
cd subfolder
ls
cd ..
touch file1
file file1
cat history1.txt
cat similar1.txt
cat similar1.txt history1.txt
grep 'in' similar1.txt
grep 'In' similar1.txt
grep 'in' *
cp similar1.txt subfolder/simcpy.txt
cd subfolder

Vim stuff (the wrong but still works way to used vim):
    Type 'vim filename' (where filename is name of your file) to open file to
        be edited. If the file already exists then it opens that file and
        displays it for you. If the file does not exists it simply creates
        and opens a blank file for you.
    Once in vim hit 'i' to get into insert mode. You know you are in insert
        mode if you see insert on the bottom of your screen.
    Use arrow keys to move cursor around while in insert mode
    To leave instert mode prest 'Esc'
    You can only edit and type things into your file while in instert mode
        (okay this is way far from true but lets pretend this is true for now)
    To save, press 'Esc' to leave insert mode and type ':w'
    To leave file press 'Esc' to leave insert mode and type ':q'. FYI vim will
        require you to save before you quit.
