VI is an editor that is natively available in the LINUX/UNIX operating system. It is rather difficult text processing tool to learn (By today’s standards). Some general notes:
1) You can only paste in “Insert Mode”
2) In “Command Mode” the keystroke “X” deletes the space to the right of the cursor
3) Hitting the “home” button puts you at the front of the current line.
I know–this is not very sexy stuff.
