Section 2.0 - Software Issues
11.) Saving and Exiting
2.4.4
Recovering Work
The VI editor edits a temporary copy of your file, and after the editing is complete, or when you tell
it to save, it puts the contents of the temporary copy into the original file. If something goes wrong
while you are editing your file, the VI editor will attempt to save whatever work you had in progress,
and store it for later recovery.
The -r option stands for recovery. If you were editing the file vitalinfo, and you accidentally got
logged out, then the -r option of the vi editor should help. The command would look somewhat like
this: vi -r vitalinfo After using the -r option once, though, you MUST save what you have recovered
to the actual file... The -r option only works once per failed VI session.
