Ceva in genul asta nu ar merge?

=== fork fun in bash ===
#!/bin/bash

# Max 'threads'
MAX=3

function next_worker() {
    # Some way to retrieve the unique ID/data/whatever for each worker
    echo $RANDOM
}

function do_work() {
    local WORKER_ID=$1
    echo "Doing work for ${WORKER_ID}..."
    sleep $[$RANDOM % 6]
    echo "Done for $WORKER_ID"
}

while :; do
    if [ `jobs|wc -l` -le $MAX ]; then
        do_work `next_worker` &
    else
        sleep 2
    fi
done
=== done with fun ===


Numai bine,
Alex
