automatically re-read from disk the current buffer

automatically re-read from disk the current buffer

[Thomas Lavergne]

Hi everyone and sorry if this is in the FAQ : I did not find it.
I am using Emacs as my editor for coding. My programs often write data 
to files for helping me during the debuging step: the content of these 
files changes at each execution. I would like to save the "OpenFile 
'foo.txt' + re-read from disk (yes)" actions. Isn't there a way to ask 
directly for re-reading from disk the current buffer?
Do I have to create a special shortcut somewhere?
Thanks in adavance.
Thomas

PS: I am using Emacs 21.2.1

Did you try in the manual?  In Emacs, most of the questions are
answered in the manual, not in the FAQ.

I think you want the command "M-x revert-buffer RET" and the
Auto-Revert mode.  You can find their description in the manual.
