You're welcome. Of course if the number of days will never vary in your
case, it would be simpler to just hard-code the number into the jq script:
# postqueue -j | jq -nr '
(now - 86400 * 5) as $too_old
| inputs
| select(.queue_name == "hold" and .arrival_time < $too_old)
| .queue_id
| select(test("^\\w+$"))
' |
postsuper -d - hold
Making it an external variable was intended to facilitate use via shell
functions that might take the day count as an option, and perhaps even
an optional list of queue names:
old_qids() {
local OPTARG OPTIND=0 days=5
while getopts hd: opt
do
case $opt in
h) echo "Usage: old_qids [-h] [-d <days>] [all | <queue> ...]" >&2
return 1;;
d) days=$OPTARG;;
*) return 1;;
esac
done
shift $(( OPTIND - 1 ))
postqueue -j |
jq -nr --argjson days "$days" '
(now - 86400 * $days) as $too_old
| $ARGS.positional as $qs
| inputs
| select(.arrival_time < $too_old)
| first(select($qs == [] or {(.queue_name,"all"):true}[$qs[]]))
| .queue_id
| select(test("^\\w+$"))
' --args -- "$@"
}
