Saving the output from individual shell scripts

I have a bash script that loops over iterations. How do i save the output from the individual scripts in the bash file according to the iteration? #Working directory cd /lustre/nobackup/WUR/ABGC/agyir001/ # Set the number of replicates num_replicates=100 # Loop over the replicates for i in $(seq 1 $num_replicates); do # replicate number with leading zeros rep_num=$(printf "%03d" $i) output_file="accuracy_results_${rep_num}.txt" #Run scenario 1,2 and 3 of male contributions Rscript Scenario_1_male_contributions.R Rscript Scenario_2_male_contributions.R Rscript Scenario_3_male_contributions.R #creating correlated qtl effects for 1000 selected qtls Rscript Correlated_qtl_effects.R #Selecting 1000 qtls, creating TBVS and phenotypes Rscript Breeding_values_and_Phenotypes.R 7500 # prepare phenotypes and genotypes/markers Rscript /lustre/nobackup/WUR/ABGC/agyir001/scripts/Markers_phenotypes_for_EBV.R
