# Generic function that utilises function arguments to fire commands for a total of `N` times in `M` jobs at a parallel

set -o xtrace

function conc(){
    cmd=("${@:3}")
    seq 1 "$1" | xargs -n1 -P"$2" "${cmd[@]}"
}

# $ conc N M cmd
# $ conc 10 2 curl --location --request GET 'http://google.com/'
# This will fire `10` curl commands at a max parallelism of two each.
# Adding this function to the `bash_profile` makes it easier.
