Re: Job queing

[Mårten Segerkvist]

Having discovering 'trap' I scripted this:

declare -a queue[]
function q() {
 address@hidden"cd `pwd` && $@"
}
function runq() {
 if [ -n "$queue" ]; then
   local command=$queue
   queue=("address@hidden:1}")
   bash -c "($command; kill -33 $$)" &
 fi
}
trap 'runq' 33

which works almost as intended...
