# this shouldn't be allowed; stdout is connected to $3 already, so if we
# replace it *and* write to stdout, we're probably confused.
echo hello world
rm -f $3
echo goodbye world >$3
user-friendliness sanity checks: catch common mistakes regarding $1/$2/$3. .do files should never modify $1, and should write to either $3 or stdout, but not both. If they write to both, it's probably because they forgot to redirect stdout to stderr, a very easy mistake to make but a hard one to detect. Now redo detects it for you and prints an informative message. 2010-11-22 04:40:54 -08:00			`# this shouldn't be allowed; stdout is connected to $3 already, so if we`
