What directory am I in right now?

pwd

Make me a new directory right here:

mkdir mydirectory

Move into that new directory that I just made:

cd mydirectory

Show me what is in this directory:

ls

Show me more information about what is in this directory:

ls -lah

Make a new blank file with this name:

touch myfile

Output this on the command line:

echo "Hello, world!"

Put that thing that I just said into the file I made before:

echo "Hello, world!" > myfile

Put this other thing that I want to say into the same file on a new line:

echo "This is another line." >> myfile

Show me what is in that file:

cat myfile

Put this thing I want to say into a totally new file:

echo "This is a third line." > myfile2

Put the stuff in this new file on a new line in my old file:

cat myfile2 >> myfile

Make a backup copy of that file:

cp myfile myfile.bck

Rename the old file to a new thing:

mv myfile mynewfile

Remove that other file that I created:

rm myfile2
