Here is "vv" that makes a backup file for you.


#!/bin/sh
if test -z "$FAVEDITOR"; then
	FAVEDITOR=/usr/ucb/vi
fi
case $# in
	0)  $FAVEEDITOR # no file, invoke editor w/o arg
		exit;;
	1)  EDITFIL=$1;;
	*)  echo "Usage:  vv [editfile]"
		exit 1;;
esac

EDITERR=editerr
TEMPFIL=/tmp/`logname`.$$
if test -r $EDITFIL; then
	cp $EDITFIL $TEMPFIL
	if $FAVEDITOR $EDITFIL; then
		mv $TEMPFIL ${EDITFIL}.bak
		echo "Backup file created"
	else
		mv $TEMPFIL $EDITERR
		echo edit error: original file is in $EDITERR
	fi
else
	$FAVEDITOR $EDITFIL
fi
