vi help, how to modify previous command
 

Is there a way to get the command in vi that I typed in previously? I am sure there must be, but I just don't know how to get it. :)

Here is an example,
I typed following command to modify the word outputofthisfile from a file

After executed, it reported that it could not find that word.. Well I realized that it should be /inputofthisfile/ instead.

I want to modify the /outputofthisfile/ to /inputofthisfile/ instead of writing the whole thing again.

use colon ( : ) to enter extended mode, then press the up arrow. vim (assuming you are actually using vim not vi) lets you see a history of commands you have run in the past.

Good luck =0)
