Vim update of the viewed file

Question

I am just wondering if I am viewing a file, for example. x.log, which is currently being updated, i.e. log file. Is there a way to effectively update it, and not: q and vim x.log again?

Answer 1

Command: e without parameters will do this.

Answer 2

: edit without any other parameters will reload the current file.

: edit! discard changes first.

Gvim will also prompt you to reload the file if you switch to another program and vice versa, and discovers that the file has been modified.

Answer 3

: autoread , .

Answer 4

: e . ! - . :

nmap <F1 > : ^ M

^ M - -M ( control-V vi).
