|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility runs the user's favourite editor
|
|
on a copy of specified file.
|
|
If no changes are made in the editor, nothing happens.
|
|
Else the original file is kept as
|
|
.Pa filename.orig ,
|
|
and the modified file
|
|
is saved as
|
|
.Pa filename.
|
|
If
|
|
.Nm
|
|
finds
|
|
.Pa filename.orig ,
|
|
it behaves as normal editor and changes are only made to
|
|
.Pa filename ,
|
|
not affecting
|
|
.Pa filename.orig .
|
|
.Sh ENVIRONMENT
|
|
.Nm
|
|
uses $PKGEDITOR if defined, then it looks for $EDITOR,
|
|
if neither is defined, it uses
|
|
.Xr vi 1 .
