I have read the example at http://www.gnu.org/software/parallel/man.html#example__calling_bash_functions however, is it possible to use gnu parallel to call 2 functions which do not have any variables you pass to them ?
example
a() {
echo "download a"
wget fileA
}
b() {
echo "download b"
wget fileB
}
and use parallel to call both functions a
& b
?
Run them in background. And then wait for them to complete.
a() {
echo "download a"
wget fileA
}
b() {
echo "download b"
wget fileB
}
a &
b &
wait # waits for all background processes to complete
