Package: debian-policy Version: 3.9.5.0 I came across this in /etc/init.d/exim4:
OLDIFS="$IFS" IFS=: for p in $PATH; do if [ -x "$p/$UPEX4CONF" ]; then IFS="$OLDIFS" $p/$UPEX4CONF $UPEX4OPTS return 0 fi done IFS="$OLDIFS" I imagine that this kind of thing is found in many other places. It seems to me that given that dash and bash both provide `type', and the underlying functionality necessarily exists in the shell, it would be better to mandate that the shell expose it. I therefore propose that the following should be added to the list of additional features listed in policy 10.4: * The XSI extension `type' must be supported . It must exit zero iff the command is found. The output format is not specified and scripts must not rely on it; scripts should rely only on the exit code using a construct such as if type foo >/dev/null 2>&1; then ...
