Hi,
I am having a hard time getting (very complex script for me) to work. The
basic idea is that this script runs a bunch of tarkets, many of which are
time consuming but low on resources (such as downloading files). Now if I
run the tarkets all at once (given some dependancy issues) it greatly speeds
up the process (about 5 time speed increase). However I do not know how to
do this using sh...
Example
#!/bin/sh
worker1() {
# Copy some files
}
worker2() {
# Download some files
}
worker3() {
# Do something else
}
..... # and so on
run_jobs() {
worker1 &
worker2 &
worker3 &
# !!! Somehow wait for over workers to finish before continuing !!!
}
#Finished
Furthermore, how can signals be handled such that the signals get
accumulated and once all the other workers have finished the signals get
passed on (appropriately)
Thank you.
David
