I have one bash script which calls the same perl script in a serial way. The bash script is used to collect the overall results, while the perl script collects the results of my simulations for the given attributes.
The bash script looks as follows:
mkdir ./results/csv && \ ../perlscripts/v2csv.pl -v -F reach results/Heterogeneous*.vec > ./results/csv/reach.csv ../perlscripts/v2csv.pl -v -F roundTrip results/Heterogeneous*.vec > ./results/csv/RT.csv ../perlscripts/v2csv.pl -v -F downlink results/Heterogeneous*.vec > ./results/csv/DL.csv ../perlscripts/v2csv.pl -v -F clusters results/Heterogeneous*.vec > ./results/csv/clusters.csv
Collecting the results by calling one perl script at a time is really long; I am looking for a way which would allow me to call the different variations of the perl script within the bash script in parallel. Is there a way to achieve this in bash?
Just to clarify, I don't want the commands which call the perl script to be dependent on each other in any way. I want all of them to start at the same point in time, as if I had 4 separate bash-terminals each executing one of these commands.
